Abstract

This work analyzes, through computer simulations, the effectiveness of the weigthed erasure decoding (WED) algorithm applied to unequal error protection block codes using binary transmission over an additive white Gaussian noise channel. The performance of the WED algorithm is compared to maximum likelihood decoding one and an evaluation of the tradeoff between performance and complexity of the WED algorithm for each class of protection is provided.
