This paper is concerned with finding the right inverse for the discrete time systems with flat rectangular transfer function matrix and individual channel power constraints. Such problem arises from various areas in control, signal processing and telecommunications. The difficulty of the problem stems from the complexity in obtaining a convex expression of the individual channel power constraints...
This paper presents a frame analysis of Zero Forcing (ZF) precoding problem. It shows that from a frame point of view, the filter bank (FB) channel is a synthesis frame and its canonical dual analysis frame is the optimal ZF precoder under total power constraint. Based on this analysis, a new precoder design is presented. The new design removes the minimum phase assumption of polyphase FB channel...
This paper investigates signal predictive quantization subject to channel loss. It uses the analysis and design tools of H∞ optimal filtering of discrete-time Markov jump linear system to obtain an optimal predictor for a signal predictive quantization system with channel loss. A linear matrix inequality (LMI) based design method is derived to design the predictor that minimizes the variance of the...
This paper is concerned with signal predictive quantization with channel loss. It uses the analysis and design tools of H2 optimal filtering of discrete-time Markov jump linear system to obtain an optimal predictor for a signal predictive quantization system with channel loss. An LMI based design method is derived to design the predictor that minimizes the variance of the reconstruction error subject...
