An adaptive, modal pam2 / pam4 - in - phases (i) - quadrature (q) - phase detector for a receiver

摘要

A phase detector comprises a data detection logic for detecting of data in a communication signal, an amplitude detection logic for processing of modulation, which consists of one of a pam2 - and a pam4 - communication modality is selected, an in - phases - flanks detection logic for detecting in - phases - edge information in the communication signal, a quadrature - flanks detection logic for detecting of quadrature - edge information in the communication signal, and mixing of the logic for determining a degree of in - phases - edge information and quadrature - edge information, which are to be used, based on at least one channel parameters in a communication channel.
