基于FPGA的π/4DQPSK调制

Based on FPGA Modulation and Demodulation ofπ/4DQPSK

π/4DQPSK调制技术是数字集群系统中一种调制方式。使用VHDL语言描述了π/4DQPSK的调制技术,并在Altera公司的CycloneⅡ系列的FPGA上实现了设计,着重介绍了FPGA上滤波器的设计。

π/4DQPSK modulation technology is one of mode of modulation in digital Trunk Communication system, π/4DQPSK modulation technology is described by language of VHDL, and the design has been achieved in FPGA of Altera＇s Cyclone II. The design of filter about FPGA is introduced extensively.
