In this paper, we propose a low-complexity method to perform the incomplete decoding needed at relays for the incomplete decode-and-forward. The decoding problem is considered as a diophantine approximation search. We propose two modifications of Cassels' algorithm to approximate an element x ?? ???(i, ??) by a linear combination a + ??b of symbols taken in a Z-PAM. Simulation results show that the...
In this work, we study the CMA-NAF protocol proposed by Azarian et al. in and propose a practical implementation. We are interested in the case of two cooperating sources which want to transmit to the same destination. In this context, two slight improvements of the protocol provide a better DMT and lower error rates. We also propose to use a decode-and-forward strategy for the same system and thus...
In this work, we explore the introduction of distributed space-time codes in decode-and-forward (DF) protocols. We propose a new Incomplete DF protocol, based on a partial decoding at the relays. This strategy allows the new protocol to bring both full diversity and full symbol rate. Outage probabilities and simulation results show that the Incomplete DF protocol has better performance than any existing...
