Description: 详细讲述了直接序列扩频差分锁相环的文章,包含具体的算法结构,并附有仿真结果。-A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential
decoder and exactly one correlator, the proposed scheme avoids
the problems of gain imbalance. The tracking error variance is
derived by linear analysis. When the proposed DCDLL scheme is
applied in ranging with additive white Gaussian noise (AWGN)
channel, the performance of the proposed DCDLL scheme is
about 1.4 dB better than that of one-correlator tau–dither loop
(TDL), and near that of noncoherent DLL. Platform: |
