自适应OFDM系统中基于分布式压缩感知的CQI反馈方案
A Method for CQI Feedback Based on Distributed Compressed Sensing in Adaptive OFDM Systems
摘要
Abstract
A compressed mechnism for channel quality indication ( CQI) feedback in OFDM systems is proposed based on distributed compressed sensing. Two joint sparse models are developed, in which the feedback data are compressed and reconstructed using compressed sensing ( CS) and distributed compressed sensing (DCS) algorithms respectively. The simulation results have shown that, compared with CS, DCS can significantly decrease the number of measurement without increasing the complexity of terminals. In this way, the goal is reached that the feedback rate of system is decreased and the throughput is increased.关键词
