The Design of a Local Optimum Non-Gaussian Receiver
In ultra-low frequency communication,due to serious interference of non-Gaussian noise,the performance of receiver which is based on the Gaussian noise becomes worse.This paper presents the design of a locally optimal receiver which is used in the non-Gaussian noise environment.It derives the FFT fast algorithm of the local optimum detection of non-Gaussian noise model and this algorithm makes full use of the FFT algorithm in computing speed,greatly reducing the computational complexity.Class B noise model is widely used non-Gaussian statistical physics model.Simulation results show that the performance of locally optimal receiver is significantly better than the conventional matched filter detector,the operation is fast and easily implemented in hardware and it has a high practical value.
