摘要: 通過對(duì)IIR信道輸出的過采樣(Oversampling),該文提出一種新的單輸入多輸出(Single-Input- Multiple-Output,SIMO)模型。較現(xiàn)有模型大大簡(jiǎn)化,可作為IIR信道盲辨識(shí)研究的依據(jù)。該文同時(shí)分析了采樣率和SIMO模型子信道數(shù)的關(guān)系,并用計(jì)算機(jī)仿真給出他們對(duì)辨識(shí)效果的影響,可作為選擇采樣率和子信道數(shù)的參考。

Abstract: A new Single-Input-Multiple-Output (SIMO) model by oversampling the output of an IIR channel is proposed. This new model is much simpler than existing one and it makes blind IIR channel identification easier to be achieved. Extensive discussions and computer simulation results are given. The efficiency and effectiveness of oversampling ratio and subchannels number of the proposed model are presented. This becomes an important cornerstone for further study in blind IIR channel identification. -
