A CMOS D-band 135–150 GHz transmitter is presented with integrated digital control and on-chip antenna. The proposed transmitter employs an IF feed-forward compensation scheme which improves the soft gain compression of the power amplifier by 5.1dB to provide an overall more linear AM-AM profile allowing reduced power back-off for modulation schemes with a high peak-to-average ratio. The proposed...
Interference is a major issue limiting the performance in wireless networks. Cooperation among receivers can help mitigate interference by forming distributed MIMO systems. The rate at which receivers cooperate, however, is limited in most scenarios. How much interference can one bit of receiver cooperation mitigate? In this paper, we study the two-user Gaussian interference channel with conferencing...
The moduli set M1=(2n,2n+1-1,2n-1) which is free of 2a+1 modulus is profitable to construct a high-speed residue number system (RNS). In this paper, we derive a reduced-complexity residue-to-binary conversion algorithm for M1 by using new Chinese remainder theorem (CRT). The resulting converter architecture mainly consists of carry-save adders (CSAs), modular adders and multiplexer (MUX) which is...
