Abstract

In this paper we investigate the combination of rate and power allocation techniques in an orthogonal cooperative scheme using infra-structured (fixed) relays, under the incremental decode-and-forward protocol. We consider realistic large scale and small scale path loss models, taking into account the antennas heights and the presence or not of line-of-sight. Results demonstrate that the throughput performance can be significantly increased in the low signal-to-noise ratio (SNR) region due to rate allocation (RA), and in the high SNR region due to power allocation (PA). In addition, we present an energy efficiency analysis which shows that RA is much more efficient than PA over the whole SNR range.

Throughout this paper, we interchangeably refer to the source as S or MS. We also refer to the destination as D or BS.

IDF presents the best performance among the DF and amplify-and-forward (AF) protocols [21]. In addition, optimum AF and compress-and-forward (CF) require more channel state information than IDF [20].

Note that since the previous direct packet was in outage, only the retransmitted packet is considered.

Note that the outage probability in (15) is lower than that of the S–D link in (8), since d < ρ and the relay antenna is at a higher height than the source antenna.

This is an usual assumption made, for instance, in [1, 18, 32].

Recall that the power allocated to the relay is given by P _R ^* = P _T − P _S ^* , since the system is subjected to a total power constraint.
