摘　　要：BPSK广泛用于卫星、微波通信、广播电视等诸多领域。近年来,随着智能卡、RFID、Bluetooth等相关技术的发展,较低码率的BPSK在近距离无线产品中也得到了越来越广泛的应用。本文设计实现了一种新型的BPSK信号调制解调器,利用m序列的随机性来产生输入基带信号,详细介绍了基于FPGA的BPSK信号调制解调器的设计方法,提供了VHDL源代码在QuartusⅡ环境下的仿真结果。整个系统的功能均在ACEXlK系列FPGA上硬件实现,具有较高的实用性和可靠性。BPSK is widely used in satellite,microwave telecommunications,broadcasting and television,etc.In recent years,as the development of related technologies of the smart CARDS,RFID,Bluetooth,low bit rate BPSK at close range wireless products also have been applied more and more.This paper designed a new type of BPSK signal modems,using m sequence of random input baseband signal to produce detailed introduced on FPGA BPSK signal modem design methods,provides simulation result of VHDL source code in Quartus Ⅱ environment.The entire system functions in ACEXlK series FPGA to hardware realization,has high practicability and reliability.
