Two classes of approximately universal codes are developed for parallel Gaussian channels whose state information is not available at the encoder. Both architectures convert the channel into a set of scalar additive white Gaussian noise (AWGN) channels to which good AWGN base codes can be applied, and both are layered schemes used in conjunction with successive interference cancellation to keep decoding complexity low. The first construction uses a concatenated code structure, and with perfectdoi:10.1109/izs.2008.4497284 fatcat:hottghpvzzgrzorbd3g4mqisqu
