摘要：In two-way relay wireless communication systems, adaptive modulation and scheduling are promising for increasing the system throughput. To achieve this goal, it is necessary to feedback the information of the channel quality indication (CQI). In this paper, we introduced a novel method for CQI feedback based on distributed compressed sensing (DCS) under orthogonal frequency division multiplexing (OFDM) system, and the feedback data are compressed and reconstructed using compressed sensing (CS) and DCS algorithm respectively. Simulation results shown that, compared with CS, DCS can significantly decrease the number of measurement under the same probability of recovery without increasing the complexity of terminals, and the throughput is increased, thus decreased the feedback expenses.
