Based on ica post processing matched filter multi - user detection lets the output of traditional matched filter to initialize the ica iterations, not only the known spread information of interesting user is used to overcome the uncertainness of ica, but also the character of statistical independence is used. the simulation results show that it advances the ability of traditional detector when the signal - noise - ratio is large. keywords code division multiple access ; independent component analysis ; channel estimation ; matched filter ; blind multi - user detection
基於ica后處理的匹配濾波多用戶檢測是用傳統的檢測器的輸出來初始化ica的迭代，它不但充分利用多用戶信號的已知信息，克服了ica的不確定性問題，同時也充分利用了多用戶信號的統計獨立性，模擬實驗結果證明這種多用戶檢測演算法在高信噪的情況下，誤碼性能改善隨著信噪比的提高不斷增加。
