Abstract A Distributed Turbo Coding (DTC) structure based on Base Station (BS) cooperation is proposed in this paper. By transmitting the data after coding through several different BS, The spatial diversity gain can be obtained at the same bandwidth efficiency, thus the communication quality of the user can be enhanced in cell boundary. Because the resources are allocated among several cell range, distributed coding structure also can improve the resource alloc success probability of the users in heavy cell. Based on the DTC structure proposed in this paper, five different realizable schemes are given, and their BER performance and resource alloc success probability are analyzed in asymmetric AWGN channel. The coding structure and realizable schemes given in this paper can also be applied to multiple BS system and distributed BS system.
