In this paper, a transmission protocol is studied for a two relay wireless network in which simple repetition coding is applied at the relays. Information-theoretic achievable rates for this transmission scheme are given, and a space-time V-BLAST signalling and detection method that can approach them is developed. It is shown through the diversity multiplexing tradeoff analysis that this transmission scheme can recover the multiplexing loss of the half-duplex relay network, while retaining some diversity gain. This scheme is also compared with conventional transmission protocols that exploit only the diversity of the network at the cost of a multiplexing loss. It is shown that the new transmission protocol offers significant performance advantages over conventional protocols, especially when the interference between the two relays is sufficiently strong.

“…In the past few years, cooperative diversity protocols [1]- [4], [7]- [12] have been studied intensively to improve the diversity of relay networks. In most of the prior work, a time-divisionmultiple-access (TDMA) half-duplex transmission is assumed and the most popular transmission protocol (e.g.…”

“…Both decode-and-forward (DF) and amplify-and-forward (AF) protocols can achieve full diversity [2], however AF transmission requires that the destination has knowledge of the channel conditions between cooperating nodes, which is not possible in many practical scenarios [3]. In this paper, we consider uncoordinated DF cooperation, according to which network nodes who successfully decode the data of some or all their partners assist them in their transmission, even though cooperation might not be reciprocal.…”

“…Resources used at one location (cell) can be reused at another place (see frequency reuse distance = cluster order 3 in figure 1 left). But also within one cell, there can be a spatial reuse by using beamforming, multipath transmission, spatial multiplexing by the use of distributed antenna elements [7].…”

Abstract-The future cellular radio networks like 3G-LTE [1] are based on an OFDMA physical layer. The duplex scheme is preferably frequency division (FDD) because of its advantages in long range. Huge area coverage in a cost-efficient way is important problem for the early deployment. Time after time the demand in densely populated areas will grow, so a higher cell capacity over the area is needed. The requirements are expensive to solve with a traditional cellular architecture, because a fibre line access will be needed at any base station location, which are sometimes only a few 100 meters apart. This paper deals with Multihop operation as an option to improve the coverage as well as the capacity issue at low cost. Homogeneous Relays act like Base Stations, but without the need of a cable or fibre access. They are simply fed by the same radio technology in their first hop.The contribution of this paper is especially the multihop operation in the FDD mode and performance results for the throughput on the MAC-layer. The results were obtained with an analytic model, numerically evaluated with Matlab.
