Summary:
A variant of successive decoding for asynchronous multiple access channel is introduced involving constant composition codebooks and maximal mutual information decoder. This admits to improve known achievability results to universal achievability, complemented by error exponents. A further result is that when synchronization is available, a deliberate shifting of the starting times of codewords (controlled asynchronism) combined with successive decoding offers a substitute for techniques of rate splitting and time sharing.
