N2 - User cooperation can provide spatial transmit diversity gains, enhance coverage, and potentially increase capacity. In this paper, incremental relaying protocol is developed. This protocol uses a limited feedback from the destination to transmitters to choose between direct transmission or cooperation. The incremental relaying protocol is examined in a space-time coded cooperation under the amplify-and-forward model. The exact bit error rate of the system is derived. Furthermore, the bit error rate of amplify-and-forward based space-time cooperation is derived, when the source-destination link is considered in both phases. Simulations demonstrate that the proposed scheme can substantially improve the spectral efficiency of the system comparing to the conventional two-phased cooperative schemes. Moreover, it is shown that the proposed scheme can achieve an outstanding coding gain in comparison to direct transmission.
