摘要
针对TDMA系统的时隙同步问题,研究了使用阵列天线的时隙同步技术,仿真结果表明,与使用单天线进行同步相比,使用阵列天线的同步方法有更好的码捕获性能,能在更低的信干噪比条件下达到相同的捕获概率。
Given the time slot synchronization technology in time division multiple access （TDMA） systems, this paper presents a technology for slot synchronization with antenna array. Simulation results show that the method with antenna array has better performance in code acquisition than that with single antenna and can achieve the same detection probability at much lower Signal - to - Interference - Noise ratio.
