阐述利用一种新的π/4-DQPSK调制快速位定时捕获算法进行低速率数字移动突发通信,并利用TMSC54xDSP芯片实现该算法的关键技术。实验表明,较之常规算法,该算法能够更加有效地克服多普勒频移并快速实现位定时捕获。
The key technology of realizing this algorithm by using a new π / 4-DQPSK modulated fast bit timing capture algorithm for low rate digital mobile burst communication is described. Experiments show that this algorithm can more effectively overcome the Doppler frequency shift and achieve bit timing capture faster than the conventional algorithm.
