This local optimized particle filtering can achieve the low MSE, and improve the precision of the MIMO-OFDM time-varying channel estimation.
與現(xiàn)有時(shí)變信道半盲估計(jì)方法相比，本方法具有估計(jì)誤差低、對(duì)非高斯噪聲頑健性強(qiáng)等特點(diǎn)，從而有效改善了接收端的符號(hào)檢測(cè)性。
The problem of channel estimation and tracking for MIMO time-varying frequency-selective channels is investigated based on training sequences.
本文主要研究了基于訓(xùn)練序列的多輸入多輸出（MIMO）時(shí)變頻率選擇性衰落信道的估計(jì)與跟蹤問(wèn)題。
