In this paper we introduce an improvement of the symbol request sharing (SRS) cooperative scheme, namely the adaptive SRS (A-SRS). Both schemes are designed for systems assuming a source and several receivers with one target receiver among them which is denoted as destination. In addition, the source or the receivers are not restricted to be static. These schemes follow a request-answer strategy, in which the destination requests specific information from the remaining receivers. With this strategy the schemes achieve spatial diversity by performing maximum ratio combining (MRC) on selected subcarriers of a coded OFDM-based system. The A-SRS complements its predecessor by adding to it more sophisticated steps in the algorithm toward its implementation on real systems. With these enhancements, the A-SRS scheme preserves the same performance as SRS for hostile source-receiver channels; nevertheless, it provides a notably enhancement for better channels conditions. In terms of BER, for instance, the A-SRS outperforms the SRS scheme by some dB's of gain and it tends to converge more slowly as the number of receivers increases. Furthermore, the A-SRS scheme adapts the length of the cooperation overhead. Therefore, it reaches the highest throughput, which is not the case for the SRS scheme.
