Improved Precoder Architecture for Duobinary Transceivers
نویسندگان
چکیده
Duobinary modulation is an attractive baseband modulation scheme for high-speed serial data transmission. This work presents a duobinary transceiver with a new precoder architecture that overcomes the glitch vulnerability of the conventional ones. It has been fabricated in a 0.13-μm PD-SOI CMOS technology and achieves 10 Gbps consuming 37 mW.

The ever growing volume of backplane communications pushes the data rate toward 20Gb/s for the next-generation transceivers. Over the years, chip designers have been seeking different data formats to overcome the loss of electrical channels. Among the existing solutions, duobinary signaling manifests itself in bandwidth efficiency as (1) its spectrum occupies only half as wide as that of NRZ da...
متن کاملEquivalence of SLNR Precoder and RZF Precoder in Downlink MU-MIMO Systems
The signal-to-leakage-and-noise ratio (SLNR) precoder is widely used for MU-MIMO systems in many works, and observed with improved performance from zeroforcing (ZF) precoder. Our work proofs SLNR precoder is completely equivalent to conventional regulated ZF (RZF) precoder, which has significant gain over ZF precoder at low SNRs. Therefore, with our conclusion, the existing performance analysis...
متن کاملHybrid Precoder and Combiner Design with Low Resolution Phase Shifters in mmWave MIMO Systems
Millimeter wave (mmWave) communications have been considered as a key technology for next generation cellular systems and Wi-Fi networks because of its advances in providing orders-of-magnitude wider bandwidth than current wireless networks. Economical and energy-efficient analog/digial hybrid precoding and combining transceivers have been often proposed for mmWave massive multiple-input multip...
متن کاملEnergy-Efficient M-QAM Precoder Design with Spatial Peak Power Minimization for MIMO Directional Modulation Transceivers
Spectrally efficient multi-antenna wireless communications is a key challenge as service demands continue to increase. At the same time, powering up radio access networks increases CO2 footprint. Hence, for an efficient radio access design, we design a directional modulation precoder for M QAM modulation with M = 4, 8, 16, 32. First, extended detection regions are defined in these constellation...
