其他书籍 Carrier-phase synchronization can be approached in a general manner by estimating the multiplicativ

Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical transmission system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet d ...
