用matlab编辑的关于超宽带通信的BPSK调制的误码率分析,系统仿真时加入高斯白噪声,仿真结果给出了时域和频域图-BER analysis of the ultra wide bank BPSK communication channel with AWGN, time and spectrum figures are given in the end.

经PPM调制的超宽带信号经高斯白噪声信道的系统仿真,给出了时域和频域图-After the PPM modulation ultra-wide band signal after the Gauss white noise channel system simulation,and give the time domain and the frequency range chart!

基于采样率变换和循环卷积的GPS信号快速捕获。提出了一种适用于GPS软件接收机的C/A码和多普勒频移的快速捕获算法。该算法结合了采样变换FFT和时域卷积两种方法，提高了捕获速度和多普勒频移的精度。-Based on the sampling rate conversion and fast circular convolution of the GPS signal capture. Presents a GPS receiver software for C/A code and Dopple
