摘要
针对二维扩频特殊的时频域扩频矩阵结构,提出了广义二维扩频矩阵的时间同步算法,并对其在瑞利衰落环境中的同步性能进行了详细的理论分析和推导。
This thesis proposes a method of time synchronization of 2D-SS system in multipath fading channels. The detection probability and false-alarm probability are analyzed and also the numerical results on condition of different normalized thresholds are presented.
