摘要
本文采用发射训练比特的方法,通过合理的数学建模,在接收端利用最小二乘估计的方法来实现超宽带信号同步。给出了详细的理论推导和MATLAB仿真结果。其同步性能由估计结果的MSE和最终的捕获概率来进行评估,仿真结果表明这种方法对于定时精度没有苛刻的要求,且利用很少比特的训练序列就可以达到相当好的同步性能。
Transmitting training bits and adopting reasonable mathematical modeling are adopted to realize UWB signal synchronization. Detail theoretical deductions and the simulation results by MATLAB are given in the paper, The performance of this synchronization method is evaluated by the MSE and the acquisition probability under different SNR, The simulation results show that this method has no demanding requirements to the timing accuracy, and it only requires limited training sequence to get good synchronization performance.
