Modulation-Induced Cyclostationarity for Blind Single-Channel Identification and Equalization with Interference-Rejection Capabilities

  • 摘要: 該文針對(duì)單輸入單輸出(Single-Input-Single-Output,SISO)信道,設(shè)計(jì)了一種特殊的引入多個(gè)共軛循環(huán)平穩(wěn)的恒模復(fù)調(diào)制方案,使得接收機(jī)只需要一個(gè)接收天線就可以對(duì)FIR信道進(jìn)行辨識(shí)(包括定階)。利用辨識(shí)出的信道,可以進(jìn)行循環(huán)維納濾波均衡,具有很強(qiáng)的抗噪聲(干擾)能力。
    Abstract: A special Modulation-Induced-Cyclostationarity (MIC) scheme is designed for the identification and equalization of FIR single channel. The scheme includes channel order determination and has the properties of interference-rejection capabilities. With the transmit power constant, the receiver needs one antenna only. The cyclic Wiener equalizer is given based on the estimated channel, which is capable of interference rejection.
