Wireless communication receiver with phase noise estimation and phase noise compensation performed after channel estimation, and related wireless communication receiving method and phase noise compensation apparatus

摘要

A wireless communication receiver includes a first signal processing block, a phase noise compensation apparatus, and a second signal processing block. The first signal processing block is arranged for generating a first processed output by processing a reception signal, wherein the first signal processing block includes a channel estimation unit arranged for performing channel estimation. The phase noise compensation apparatus is arranged for receiving the first processed output and generating a second processed output by performing phase noise compensation according to the received first processed output. The second signal processing block is arranged for receiving the second processed output and processing the received second processed output.
