一种基于互质采样的相关检测算法

In the application of signal detection, with the increase of signal frequency and bandwidth, the sampling frequency is increased, and the amount of data processing is increasing. To solve this problem, this paper proposes a detection algorithm based on coprime sampling method. By means of the method of the detected signal splitter, coprime sampling is adopted, to ensure low signal to noise ratio based on the detection performance of the greatly reduced the required sampling frequency. Theoretical analysis and simulation results show that correlation detection algorithm based on coprime sampling not only has good detection performance, and greatly reduce the system sampling rate and algorithm complexity.
