Performance of space-time block coding under impulsive noise environment

In this paper, we investigate the performance of orthogonal space-time block coding (OSTBC) under impulsive noise environment, the joint probability density function (pdf) of the noise signals in OSTBC systems is presented with statistical-physical Middleton Class A noise model. We derive the upper bound on the average pairwise error probability (PEP) under Class A noise environment by the moment generating function (MGF), and also evaluate the performance of symbol error rate (SER) over fading channels. It is observed that the performance of OSTBC will be degraded as the impulsive nature of the noise increases in Class A noise environment.
