摘要

在fpga中实现了一个非常简单的基于lms的自适应陷波滤波器，可用于QPSK信号的载波恢复和BPSK信号的直接检测。本文的重点在于载波频率检测或同步电路的替代实现方法。传统的QPSK检波器采用检测后的载波频率。此外，该解调器具有简单的硬件实现，不需要参考信号。

Hardware efficient BPSK and QPSK detector

A very simple LMS-based adaptive notch filter implemented in FPGAs can be used for carrier recovery of a QPSK signal and for direct detection of a BPSK signal. The key aspect of our paper lies in the alternative approach in the realization of carrier frequency detection or synchronization circuit. The carrier frequency after detection is used in the conventional QPSK detector. Also the demodulator has a simple hardware realization that does not require a reference signal.
