Abstract: The space-time cooperative diversity scheme based on liner dispersion codes outperforms in BER performance the traditional OSTBC cooperative diversity scheme in a high rate system. By selecting different rate liner dispersion codes, the system can trade off between BER performance and data rate. Compared with the system adopting a lower rate liner dispersion code, when the channel condition is good between the source and relays, the system adopting a higher rate liner dispersion code can gain a higher data rate by sacrificing the BER performance just a bit.

Key words: liner dispersion codes, cooperative diversity, relay, OSTBC
