Joint Channel-Estimation/Decoding with Frequency-Selective Channels and Few-Bit ADCs
Peng Sun, Zhongyong Wang, Robert W. Heath +1
We propose a fast and near-optimal approach to joint channel-estimation, equalization, and decoding of coded single-carrier (SC) transmissions over frequency-selective channels wit…
