IEEE Transactions on Communications, 57(8), pp. 2330-2338.http://hdl.handle.net/10092/4039This paper investigates the design and performance of a two-user satellite communication system. Each user is independently encoded using a structured Turbo code with identical symbol interleavers. This permits Turbo decoding to be performed using the combined component code trellises, which provides significant gains over independent decoding. The design of the code-matched symbol interleavers is described. Both ideal and imperfect knowledge of the relative phase shift between users is considered. Performance is compared to the single user case and the performance degradation due to a third unknown user is considered. These investigations show that the proposed system performs well in a variety of conditions.enturbo codesatellite communicationsinterleaver designiterative decodingmultiuser communicationJournal ArticleFields of Research::290000 Engineering and Technology::291700 Communications Technologies::291709 Satellite communications
