摘要: 该文针对单输入单输出(Single-Input-Single-Output,SISO)信道,设计了一种特殊的引入多个共轭循环平稳的恒模复调制方案,使得接收机只需要一个接收天线就可以对FIR信道进行辨识(包括定阶)。利用辨识出的信道,可以进行循环维纳滤波均衡,具有很强的抗噪声(干扰)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. -
