摘要

我们分析了带反馈的移动无线电信道的新型多分辨率联合信源和信道编码（MR-JSCC）方案的性能。发射机和接收机可根据信道状态信息（CSI）同步匹配彼此的分辨率。通过仔细调整分辨率阈值，可以满足带宽要求。本文概述了阈值确定算法。仿真结果表明，在相同带宽和功率条件下，MR-JSCC 方案的性能远远优于基线 I（无 UEP 和无反馈）和基线 II（无反馈的 UEP）。

Performance analysis of multiresolution joint source-channel coding for mobile radio channels with feedback

We analyze the performance of a novel multiresolution joint source and channel coding (MR-JSCC) scheme for mobile radio channels with feedback. The transmitter and receiver can match the resolution of each other synchronously, according to the channel state information (CSI). Bandwidth requirements can be met by carefully adjusting the resolution thresholds. The threshold determination algorithm is outlined. Simulation results show that MR-JSCC scheme has much better performance than baseline-I (no UEP and no feedback) and baseline-II (UEP without feedback) at the same bandwidth and power.
