MPSK调制体制在黑障信道下的MATLAB/Simulink仿真(MPSK modulator simulate in blackout using MATLAB/Simulink)

基于Costas编码的跳频信号的互相关时延估计，matlab版本：2013a(Delay estimation based on cross-correlation coding Costas frequency hopping signals, matlab version: 2013a)

Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS).
