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 this paper, we introduce the symbol request sharing (SRS) cooperative scheme. Assuming a system with one source and several receivers, spatial diversity can be achieved by performing maximum ratio combining (MRC) on selected subcarriers of a coded OFDM-based system. The receivers are physically separated from each other and not restricted to be static. Furthermore, any receiver can be configured...
