Abstract

As a significant non-Gaussian distribution and impulsive noise model, alpha-stable distribution has been widely used in signal processing, since its probability density function (PDF) has heavy tails which corresponds with the impulsive noise samples in the time domain. In this letter, the geometric power of the symmetric alpha-stable (S

$\alpha $

S) noise passing through the Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) systems on Rayleigh fading channles is derived and the bit error rate (BER) of the DFT-S-OFDM systems on Rayleigh fading channels with S

$\alpha $

S noise is further derived. Based on a proposed selection criterion, two approximation models of BER are jointly applied for computational efficiency. Simulation results demonstrate that the derived theoretical and approximate BERs both agree well with the simulated BER curves under various system parameters and impulsive noise conditions.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
