Abstract

We propose a channel estimation technique based on an expectation maximization (EM) algorithm, for space-time block coded (STBC) multi-input multi-output (MIMO) OFDM systems. The channel estimation is done by decomposing the superimposed received signals, into their signal components and estimating the channel parameters of each signal component separately

基于em的空时分组编码MIMO OFDM系统信道估计

针对空时分组编码(STBC)多输入多输出(MIMO) OFDM系统，提出了一种基于期望最大化(EM)算法的信道估计技术。信道估计是通过将接收到的叠加信号分解成信号分量，并分别估计每个信号分量的信道参数来完成的
