摘要
针对全数字接收机研究中的定时提取技术 ,对数字滤波和近最佳定时提取算法进行了新的改进 ,通过计算机摸拟表明改进后的算法具有收敛速度快、抖动小、抗载波固定相差和运算量小等特点。
This paper researched the timing extraction technique in the implementation of the all digital receiver in detail. A modified timing extraction algorithm was proposed, which has the following advantages: fast convergence, better anti_jamming performance and anti_fixed phase difference of the carrier. The timing convergence curve of the new timing algorithm is nearly smooth.
