Abstract: -Recent wireless systems such as EDGE, WIMAX, LTE are using LDPC, tail biting and turbo convolution codes as the forward error correction codes (FEC) for the data and overhead channels. Therefore many decoding algorithms are introduced for decoding these codes. Using different decoding approaches lead to different hardware architectures. As, in new wireless systems these codes work side by side a single universal decoder which is efficient in handling decoding of all the codes.
