Abstract :
In this paper, we modify background noise of multi-user detection, by selecting non-Gaussian noise of more harshly conditions such as Laplace noise and Alpha-Stable noise. Under the traditional MMSE algorithm, Comparing the BER of the two noises with Gaussian noise, which can get close to real complex environment and be beneficial to further research.
