Study on MIMO-TDCS Time-frequency Compressed Sensing Feedback Scheme

摘要:

为突破传统多输入多输出变换域通信(MIMO-TDCS)要求电磁环境一致性的技术瓶颈, 将MIMO-TDCS的强抗干扰能力拓展到复杂电磁环境通信领域, 建立了一种基于时域、频域二维压缩的MIMO-TDCS时频压缩感知(TFCS)反馈模型, 分析了TFCS的性能。仿真结果表明, TFCS模型较传统模型所需数据更少, 在一定条件下具有良好的检测效果。

Abstract:

In order to break the technical bottleneck of MIMO-TDCS in electromagnetic environment and extend the strong anti-interference of MIMO-TDCS to communications in complex electromagnetic environment, a two-dimensional compression Time-Frequency Compressed Sensing (TFCS) model is established based on the time and frequency domain, and the performance of TFCS is analyzed. Simulations show that TFCS needs less transmitted data than the traditional model on the same detection probability and the performance is better under certain conditions.
