“…Unlike [11], [12], [15], [16], where the fixed-gain amplifyand-forward protocol is used at relay because of the assumption that the instantaneous CSI of S → R channel is absent at relay, and the relay directly amplifies the received signal Y 1 with a scaling factor and forwards the scaled signal to destination, in our scheme we assume that the instantaneous CSI of S → R channel is available at the relay and the adaptive-gain amplify-and-forward protocol can be used at relay [4], [20], but without amplifying Y 1 directly. In particular, the relay amplifies 1, , = 1, 2, .…”

“…One category assumes that the relay is lacking of the instantaneous CSI of source-to-relay channel and employs fixed-gain (noncoherent) AF protocol. Ergodic capacity of two-hop and cooperative (two-hop with source-to-destination channel) fixed-gain AF MIMO relaying is analyzed in [11] and [12], respectively. Performance analysis of OSTBC transmission for two-hop and cooperative fixed-gain AF MIMO relaying is presented in [15] and [16], respectively.…”

We propose a cooperative orthogonal space-time block codes (OSTBC) transmission scheme in the adaptive-gain amplify-and-forward MIMO relaying with S source antennas, R relay antennas, and D destination antennas, and analyze the asymptotic performance of the proposed scheme. Specifically, we explore the instantaneous channel state information (CSI) of source-to-relay channel and design an OSTBC transmission scheme by reconstructing the compound source-relay-destination channel. The asymptotic analysis in terms of symbol error rate (SER) in high SNR regime shows that the proposed scheme can achieve the diversity order S D + R min{ S, D}. Numerical results that confirm our analysis are also presented in the paper.

“…In the original AF scheme [4], [8], the RN is used as a simple equal gain (EG) amplifier. In the general case, an intricate computable formula of the channel capacity for AF EG system has been derived in [9]. Whereas a simple asymptotic closed-form approximation of the channel capacity for AF EG system has been derived in [10] by assuming that the SN-DN link, i.e.…”

Abstract-Cooperative communication is an effective approach for increasing the spectral efficiency and/or the coverage of cellular networks as well as reducing the cost of network deployment. However, it remains to be seen how energy efficient it is. In this paper, we assess the energy efficiency of the conventional Amplifyand-forward (AF) scheme in an in-building relaying scenario. This scenario simplifies the mutual information formulation of the AF system and allows us to express its channel capacity with a simple and accurate closed-form approximation. In addition, a framework for the energy efficiency analysis of AF system is introduced, which includes a power consumption model and an energy efficiency metric, i.e. the bit-per-joule capacity. This framework along with our closed-form approximation are utilized for assessing both the channel and bit-per-joule capacities of the AF system in an in-building scenario. Our results indicate that transmitting with maximum power is not energy efficient and that AF system is more energy efficient than point-to-point communication at low transmit powers and signal-to-noise ratios.

Abstract-The paper presents an ergodic capacity analysis of MIMO three product channels. We first derive the exact non-asymptotic and asymptotic probability density functions of the arbitrary eigenvalue of the system. From these, a nonasymptotic and asymptotic expression for the ergodic capacity of the system is derived. The non-asymptotic results involve several single numerical integrations and the number of numerical integrations increases with the number of antennas used in the system. However, the asymptotic result has only one numerical integration and a more compact form, hence providing a simpler alternative to the non-asymptotic ergodic capacity result. We also validate the results by using simulations. The results show that the non-asymptotic analytical results are in good agreement with the simulations and the asymptotic analytical results provide a good approximation to the exact results even when the system has very few antennas.
