报告内容:In this talk, we introduce a general framework for analyzing and designing communication systems subject to transceiver nonlinearities. This framework is based on mismatched decoding. The output processing of linearization provides an information-theoretic interpretation of Bussgang’s decomposition, while the output processing of minimum mean square error (MMSE) estimation further improves performance, and is connected to the concept of correlation ratio by Renyi. The analytical results are illustrated by a case study of massive MIMO under coarse output quantization.
