Performance of DMT Systems Under Impulsive Noise

The performance of DMT systems is studied in impulsive noise channels by using Middleton's Class A noise distribution. A statistical model is developed to generate Class A distributed impulsive noise samples and this model is used for the performance analysis. An exact expression is derived for the subchannel SER. By employing the central limit theorem, the subchannel SER is further simplified. The results are presented as a function of the effective subchannel SNR for different values of impulsive noise index.
