Abstract

Cooperative transmission schemes have recently been proposed to improve the uplink performance of wireless communications systems by increasing diversity without requiring use of multiple transmit antennas. We here propose a novel cooperative scheme that performs distributed coding of user data, uses only one channel per user and allows a flexible trade-off between rate and diversity, thus achieving higher data rates than previously proposed coded cooperative schemes. The point of operation of the system on the diversity-rate curve can be arbitrarily chosen according to the number of cooperating users. A trade-off is increased complexity as more users are required to be simultaneously decoded by the BS. We describe the construction of the distributed code for a n-user system, that results in reduced complexity decoding operations at the BS. The performance of the proposed method is studied via analytical bounds and numerical simulations.
