摘要

迭代信道估计和译码可以显著提高性能，但计算成本较高。本文提出了一种迭代信道估计控制方法，通过对影响译码性能的信道估计进行细化来降低算法复杂度。仿真结果表明，在错误率可以忽略不计的情况下，可以实现显著的复杂性节约。

Iterative channel estimation control for MIMO-OFDM Systems

Iterative channel estimation and decoding result in significant performance gains but at high computational cost. In this paper, an iterative channel estimation control is proposed to reduce the complexity by only refining the channel estimates which significantly affect the decoding performance. Simulation results demonstrate that significant complexity savings can be achieved with negligible error rate performance loss.
