Abstract
This paper considers a more general additive noise distribution, termed either as generalized Laplacian (GL) or McLeish distribution whose non-Gaussianity nature is parameterized to fit different impulsive noise environments, and analyzes the bit-error rate of binary phase shift keying modulation over additive white GL noise (AWGLN) channels in flat fading environments. Specifically, a closed-form expression is offered for the extended generalized-K fading environments, and accordingly, its simplifications for some special fading distributions and special additive noise models are presented. Finally, the mathematical formalism is illustrated by numerical examples, and verified by computer based simulations.
