摘要

A Differential quadrature phase shift keying (DQPSK) modulator and demodulator system incorporating surface acoustic wave (SAW) device is presented. The SAW device in the modulator consists of four delay lines corresponding to different phase delays and generates phase shift keyed radio-frequency signals. In the demodulator section, another SAW device performs addition operation between two consec...
