최근, 새롭고 다양한 이동통신 서비스의 대거 출현으로 언제 어디서나 누구나 이용할 수 있는 서비스의 대중화와 아울러 선택의 시대가 본격적으로 열려 차세대에는 고도정보화 사회를 맞이하여 이동통신의 역할이 더욱 커질 전망이다.Recently, with the emergence of new and diverse mobile communication services, the age of choice is opened in earnest as well as the popularization of services that can be used by anyone at any time and any place, and the role of mobile communication is expected to grow further in the next generation.

그러나 다양하게 개발된 현재의 이동통신 서비스는 각각의 서비스마다 구현하는 기술방식이 다르고 같은 기술이더라도 국가나 지역마다 사용하는 주파수대역이 달라 무선통신 고유의 장점인 이동성을 완벽하게 실현하는데 근본적인 한계를 가지고 있다.However, various currently developed mobile communication services have different technical methods to implement each service, and even though the same technology has different frequency bands in each country or region, there are fundamental limitations in fully realizing mobility, which is inherent in wireless communication. have.

또한, 무선이라도 전송매체를 사용해야 하는 기술적인 제약으로 인해 멀티미디어 서비스와 같은 이용자의 증대한 욕구를 만족시키기에는 근본적인 어려움이 있었으며 이러한 기존 이동통신 서비스의 한계를 극복하기 위하여 등장한 것이 IMT 2000이다.In addition, there is a fundamental difficulty in satisfying the increased needs of users, such as multimedia services, due to technical limitations on the use of a transmission medium even in wireless, and the IMT 2000 appeared to overcome the limitations of the existing mobile communication service.

이러한 IMT 2000은 각종 이동통신 서비스를 하나로 통합하여 무선의 ISDN화를 이룰 수 있으며, 기존의 이동전화망이 진화, 발전된 차세대 이동통신 시스템으로서 유선망 수준의 품질을 갖는 무선멀티미디어 서비스를 제공할 수 있다.The IMT 2000 can achieve a wireless ISDN by integrating various mobile communication services into one, and can provide a wireless multimedia service having a wired network quality as a next generation mobile communication system in which an existing mobile telephone network has evolved and developed.

이와 같은 IMT 2000 또는 CDMA 2000에 있어서는, 채널 밴드 폭이 DCS의 경우 1X:1.23MHz, 2X:2.46MHz, 3X:3.69MHz이고, PCS의 경우에는 1X:1.25MHz, 2X:2.5MHz, 3X:3.75MHz가 된다.In IMT 2000 or CDMA 2000, the channel bandwidth is 1X: 1.23MHz, 2X: 2.46MHz, 3X: 3.69MHz for DCS, and 1X: 1.25MHz, 2X: 2.5MHz, 3X: 3.75 for PCS. MHz.

그러나 최근 CDMA 2000(IMT 2000)으로 발전하면서 채널 밴드 폭이 DCS의 경우에는 1X:1.23MHz, 2X:2.46MHz, 3X:3.69MHz, PCS는 1X:1.25MHz, 2X:2.5MHz, 3X:3.75MHz로 1X의 배수만큼 넓어지면서 기존의 DCS, PCS방식을 수용함과 함께 CDMA 2000(IMT 2000)서비스를 해야 하는 문제가 발생한다.However, with the recent evolution to CDMA 2000 (IMT 2000), the channel bandwidth is 1X: 1.23MHz, 2X: 2.46MHz, 3X: 3.69MHz for PCS, 1X: 1.25MHz, 2X: 2.5MHz, 3X: 3.75MHz for DCS. As it is widened by multiples of 1X, the existing DCS and PCS schemes must be accommodated and CDMA 2000 (IMT 2000) services must be provided.

즉, 종래 DCS, PCS방식에 있어서는 채널 밴드 폭이 1X:1.23MHz, 1.25MHz로되어 있어 이 방식으로는 밴드 폭이 좁아 CDMA 2000 또는 IMT2000의 서비스를 수행할 수 없는 결점이 있었다.That is, in the conventional DCS and PCS schemes, the channel band widths are 1X: 1.23 MHz and 1.25 MHz, and thus, the band width is narrow in this scheme, and thus the CDMA 2000 or IMT2000 service cannot be performed.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 본 발명의 목적은, 멀티 캐리어 혼용 수신기를 사용하여 밴드 폭을 3X로 사용함으로써 밴드 폭을 넓혀 기존의 DCS, PCS방식을 수용할 수 있음은 물론 CDMA 2000(IMT 2000)서비스까지도 효과적으로 수행할 수 있도록 하는 멀티 캐리어 방식의 혼용 수신장치를 제공하는데 있다.The present invention has been made to solve such a conventional problem, an object of the present invention, by using a multi-carrier mixed receiver in a band width of 3X to widen the band width to accommodate the existing DCS, PCS scheme In addition, the present invention provides a multi-carrier hybrid receiver capable of effectively performing CDMA 2000 (IMT 2000) services.

이하, 본 발명의 실시 예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 블록도로, 수신된 1X입력신호와 1X 로컬 신호를 믹싱하여제1 중간주파수(IF)를 출력하는 제1믹싱부(10)와, 수신된 2X입력신호와 2X 로컬 신호를 믹싱하여 제2 중간주파수(IF)를 출력하는 제2믹싱부(20)와, 수신된 3X입력신호와 3X 로컬 신호를 믹싱하여 제3 중간주파수(IF)를 출력하는 제3믹싱부(30)와, 상기 제1내지 제3믹싱부(10∼30)의 출력신호를 필터링하는 소 필터(SAW FILTER)(40)와, 상기 소 필터(40)의 출력신호를 공통 제2 로컬 신호와 믹싱하는 제4내지 제6믹싱부(50∼70)와, 상기 제4내지 제6믹싱부(50∼70)의 출력을 결합하여 출력하는 결합기(80)로 구성된다.1 is a block diagram of the present invention, a first mixing unit 10 for outputting a first intermediate frequency (IF) by mixing the received 1X input signal and 1X local signal, and the received 2X input signal and 2X local signal A second mixing unit 20 for mixing and outputting a second intermediate frequency IF, and a third mixing unit 30 for mixing a received 3X input signal and a 3X local signal and outputting a third intermediate frequency IF. And a small filter 40 for filtering the output signals of the first to third mixing units 10 to 30, and the output signal of the small filter 40 with a common second local signal. And a combiner 80 configured to combine and output the outputs of the fourth to sixth mixing units 50 to 70 and the fourth to sixth mixing units 50 to 70.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

먼저, 1X, 2X, 3X DCS:1.23MHz, PCS:1.25MHz의 간격을 가진 채널이 기지국에 수신되어 수신기에 입력된다.First, a channel having an interval of 1X, 2X, 3X DCS: 1.23MHz and PCS: 1.25MHz is received at a base station and input to a receiver.

이렇게 수신된 입력이 1X, 2X, 3X 로컬단을 통하여 제1믹싱부(10)내지 제3믹싱부(30)에서 각각 자기의 채널 로컬 주파수와 믹싱되어 제1 중간주파수(IF)로 변환된다.The received input is mixed with its channel local frequency in the first mixing unit 10 to the third mixing unit 30 through the 1X, 2X, and 3X local stages, respectively, and converted to the first intermediate frequency IF.

또한, 상기 제1믹싱부(10)내지 제3믹싱부(30)에 의해 믹싱된 제1 중간주파수(IF)는 각각 소 필터(탄성 표면파 필터)(40)를 통하면서 소 필터링(Saw Filtering)된다.In addition, the first intermediate frequency IF mixed by the first mixing unit 10 to the third mixing unit 30 passes through a small filter (elastic surface wave filter) 40, respectively. do.

그리고 이와 같이 소 필터(40)를 통하여 소 필터링된 채널신호는 제4내지 제6믹싱부(50∼70)를 통하여 공동으로 사용하는 제2로컬 주파수와 믹싱되어 제2중간주파수(IF)로 변환된다.In this way, the small channel filter filtered through the small filter 40 is mixed with a second local frequency commonly used through the fourth to sixth mixing units 50 to 70 to be converted into a second intermediate frequency IF. do.

이와 같이 제4내지 제6믹싱부(50∼70)를 통하여 믹싱된 제2중간 주파수(IF)는 결합기(80)를 통하여 결합되어 3X 밴드 폭을 갖는 채널로 출력하게 된다.As such, the second intermediate frequencies IF mixed through the fourth to sixth mixing units 50 to 70 are combined through the combiner 80 and output to the channel having a 3X band width.

즉, 기존의 DCS, PCS방식에서는 1X(1.23 또는 1.25MHz)만 사용하고자 할 경우에는 2X, 3X로컬 주파수를 차단하면 되었으나, 본 발명의 CDMA 2000방식에 있어서, 밴드 폭을 3X만 사용하고자 할 경우에는 1X, 2X, 3X 로컬 주파수를 입력하면 3X(DCS 3.69MHz, PCS 3.75MHz) 밴드폭을 갖는 채널을 출력할 수 있게 되는 것이다.That is, in case of using only 1X (1.23 or 1.25MHz) in the existing DCS and PCS methods, the 2X and 3X local frequencies need to be cut off, but in the CDMA 2000 method of the present invention, when only 3X is used for the bandwidth If you input 1X, 2X, or 3X local frequencies, you can output channels with 3X (DCS 3.69MHz, PCS 3.75MHz) bandwidth.

따라서, 본 발명은 상술한 바와 같은 방법에 따라 멀티 캐리어 방식의 1X, 2X, 3X 혼용 수신기를 구현할 수 있는 것이다.Accordingly, the present invention can implement a multi-carrier 1X, 2X, 3X mixed receiver according to the method described above.

이상에서 설명한 바와 같은 본 발명은 멀티캐리어 방식의 1X, 2X, 3X를 구현할 수 있어 기존의 DCS, PCS의 1X방식으로 구현할 수 없는 CDMA 2000(IMT 2000)을 구현할 수 있으며, 서비스 사업자가 그 지역에서 기존의 방식으로 서비스 사업을 할 것인지 또는 CDMA2000서비스를 할 것인지를 선택할 수 있는 효과가 있다.As described above, the present invention can implement a multicarrier type 1X, 2X, and 3X, and thus can implement CDMA 2000 (IMT 2000), which cannot be implemented using a 1X type of a conventional DCS and PCS, and a service provider in the region. There is an effect that you can choose whether to do service business or CDMA2000 service in the existing way.
