In this letter, the authors develop exact analytical expressions for the average signal-to-noise ratio (SNR), ergodic capacity, and average bit-error-rate (BER) performance of a THz wireless link under the combined effect of α- μ fading channel, zero-boresight pointing errors, and the Gaussian distributed #transceiver #hardware #impairment (#THI). The authors also derive asymptotic expressions for the outage probability and average BER, which shows that the diversity order of the THz link is independent of THI’s parameters. ---- Pranay Bhardwaj, S.

How to Classify 10G SFP+ Transceiver Modules? The purpose of this article is to provide a brief introduction to 10G SFP+ optical modules, so that readers can have a clear categorization of 10G SFP+ optical modules. https://lnkd.in/gKZfSDx5

This work presents a novel optimization framework for the joint #true-#time #delay (#TTD) and #phase #shifters (#PS) precoder design, incorporating realistic time delay constraints for each TTD device to mitigate the aforementioned beam squint effect in wideband #sub-#Terahertz (#sub-#THz) massive #multiple-#input #multiple-#output (#MIMO) communication systems. Unlike previous methods, their framework does not rely on the unbounded time delay assumption and optimizes the TTD and PS values jointly to cope with the practical limitations. Furthermore, within the context of their proposed framework, they mathematically determine the minimum number of TTD devices necessitated to achieve a predetermined target array gain. ----Dang Qua Nguyen, @Taejoon Kim More details can be found at this link: https://lnkd.in/edkWgR6J

This paper proposes a novel phase calibration method to cancel out both the random and systematic time-invariant phase offsets at the superheterodyne receiver frontends. Direct phase offset measurements and on-site calibration are made possible by additional hardware connections, achieving simple implementation and accurate differential phase measurements without relying on bandwidth resources. This method can also be flexibly extended to accommodate a broad range of practical network scenarios with more channels, various network topologies, and a wider bandwidth. ----许郭译 More details can be found at this link: https://lnkd.in/gsg-g9Vq

Why Do Optical Modulators Require Bias Voltage Optimization? Properly optimizing bias voltage in optical modulators directly impacts telecommunication system performance, efficiency, and reliability. A few key benefits include: > Reduced Bit Error Rate (BER) > Good signal-to-noise ratio (SNR) maintained > Operation in a linear input signal response region > Minimized distortion, signal loss, channel crosstalk, and interference Learn more by clicking on the link in the Comments section to access the full Application Note. #testandmeasurement #opticalcommunications #fiberoptics #telecommunications #optical

Comparison of two protection schemes for OLP OTN OLP advantages: Deployment is quick based on existing routing, just replace the expansion card and add a protection card. The cost is low and there is no need to significantly change the current equipment. In case of double-core line failure, 100% automatic routing is guaranteed. Disadvantages: In the current network environment, line attenuation increases, single-core interruptions and other conditions are not sensitive. Manual switching is required according to the situation and requires personnel to be on duty. OTN advantages: Configure the conditions for route switching according to the trigger type (such as LOS, LOF, LOM, AIS, TTI, LCK, etc.). Switch to the backup route 100% when the trigger conditions are met. High reliability and no need for human supervision. Shortcoming: Equipment needs to be replaced, which is time-consuming and labor-intensive, and the current cabinet space is insufficient. The cost is high.

This paper presents a single-element #linearly #polarized (#LP) patch antenna characterized by a wide impedance bandwidth and low profile, optimized for 5G V2X applications. By inserting air gaps into the LP patch antenna structure, a #circularly #polarized (#CP) antenna is generated. Moreover, a cross-stubs technique is employed to generate CP from LP, thereby enhancing the #axial #ratio (#AR) bandwidth. ---- Khaled A.
