基于FPGA的QPSK调制解调电路设计与实现

Design and Realization of QPSK Modulation and Demodulation Circuit Based on FPGA

数字调制解调技术在数字通信中占有非常重要的地位,数字通信技术与FPGA的结合是现代通信系统发展的一个必然趋势。文中介绍了QPSK调制解调的原理,并基于FPGA实现了QPSK调制解调电路。MAX+PLUSⅡ环境下的仿真结果表明了该设计的正确性。

Technology of digital modulation and demodulation plays a important role in digital communication system, the combination of digital communication technology and FPGA is a certainly trend .The paper introduces the principle of QPSK modulation and demodulation, the circuit are also be realized based on FPGA. The simulation result under MAX＋PLUSII environment provides the correction of the design.
