1. Projeto de EntrelaÃadores para cÃdigos turbo
Interleavers perform a central role in the near channel capacity performance of turbo codes. Besides been introduced as simple random permutations, nowadays there are several classes of interleavers like s-random, DRP, polynomial, and quasi-cyclic that provide a better performance for turbo codes in an AWGN channel and/or are simpler to store. This work has

2. CodificaÃÃo iterativa para o canal adtivo com dois usuÃrios binÃrios
This thesis is concerned with an investigation of iterative coding schemes for the two-user binary adder channel (2-BAC). A coding scheme is introduced for the 2-BAC using a single convolutional code which permits efficient decoding. The constructed two-user trellis codes have a significant practical advantage because iterative decoding techniques used in th
