Generation and Estimation of Parameters of Simplified Middleton Class B Noise

Conventional linear receivers which are effective and optimum for white Gaussian noise can drastically degrade the performance or even made ineffective when operating against non-Gaussian noise. On the other hand, the performance of communications operating in such impulsive channels can be greatly enhanced if the true statistics of the channel are known and exploited. The Middleton interference model is statistical-physical and parametric model for man-made and natural electromagnetic (EM) interference. In this letter, the efficient estimation of the Class B model parameters based on least square gradient method is derived. The considered estimator is fast converges and low-complexity with performance approaching theoretical optima for large data samples. Simulation of this estimator with three unknown parameters indicates that this technique is efficient.
