Abstract :
A generalized multiuser cooperative concatenated coding framework is theoretically developed for not only cooperative diversity but also enhanced distance spectra. Novel schemes are proposed featuring flexible cooperation group, variable-size messages, and other practical concerns. In particular, users failing to detect their partners messages are allowed to cooperate without incurring error propagation.
