基于MCM的多径非相关无线信道改进模型研究

In order to improve the statistical properties of multipath fading and more accurate description of wireless channel. This paper proposed an improved simulation model based on Monte Carlo method (MCM) for uncorrelated multiple Rayleigh fading channels. Based on the angle of arrival (AOA) , the multipath element (k) is introduced into the new simulation model, which improved theethod of evaluating AOA. Through the simulation analysis of the channel model parameters AOA, k, the number of low frequency oscillator and the mean square error (MSE) , the results show that a pretty good agreement statistical property of the new model and those of the underlying reference model has been observed. Compared with MCM, the new model has a significant improvement in the autocorrelation properties in the same conditions and the MSE is about a quarter of the original. The new method is useful for the design of wireless channel simulator, frequency-selective channel.
