Sum-of-sinusoids-based simulator for Nakagami-m fading channels

Fading signals due to multipath in wireless channels are widely modeled by a sum-of-sinusoids-based simulator owing to simplicity and frugality. Although this class of techniques have gained widespread acceptance, few studies apply it into the Nakagami-m fading channel. The primary reason why the Nakagami-m fading channel is getting more popular lies in its good fit for empirical data. Furthermore, the sum of the mutually exclusive Hoyt and Ricean models is the Nakagami-m fading distribution. Therefore, the goal of this paper is offering a novel Nakagami-m fading simulator with its analysis of the statistical stationary squared-envelope autocorrelation function. Moreover, a modification with Walsh-Hadamard coding to the new model is also proposed to create multiple uncorrelated fading envelopes.
