Title: 差分编码OQPSK调制解调器设计_刘圣慧 Download
 Description: OQPSK modulation performance is much better than QPSK, but due to the particularity of OQPSK modulation, its differential encoding and decoding are relatively complex The principle of differential codec and modulation demodulation of doqpsk is deeply analyzed. Aiming at the problems of traditional coherent demodulation and decoding methods of doqpsk, the A simple and efficient method to improve the demodulation and decoding of doqpsk. This method not only has simple structure, but also eliminates 3dB solution compared with DQPSK demodulation The problem of modulation loss greatly improves the demodulation performance of the system.
