“…It should be mentioned that with instantaneous feedback, the multiuser TAS/MRC system can achieve a full asymptotic diversity order of KM T M R [3]. Comparing the different results of the outdated feedback case and the instantaneous feedback case, one may conclude that with outdated feedback, the closed-loop transmit diversity order and multiuser diversity order asymptotically reduce to one.…”

“…In the multiuser TAS/MRC system, the spatial diversity and multiuser diversity can be exploited simultaneously to enhance the performance. To be specific, the users perform MRC, and at the transmitter, only one antenna of the base station (BS) and one user that lead to the largest effective SNR are selected for data transmission [3].…”

“…Then in [5], the authors extended the analysis of [4] by considering the generalized Nakagami fading channels. For the multiuser TAS/MRC system, the outage probability was investigated in [3] for the Rayleigh fading channels and in [6] for the Nakagami fading channels, respectively. Moreover, the outage capacity of the multiuser TAS/MRC system was studied in [7], while the average capacity was analyzed in [8].…”

“…Moreover, the outage capacity of the multiuser TAS/MRC system was studied in [7], while the average capacity was analyzed in [8]. It has been established in [3] and [6] that the diversity order at high SNRs of the multiuser TAS/MRC system is improved in proportion to the number of users, the number of transmit antennas at the BS as well as the number of receive antennas at the users; specifically, the users can be viewed as equivalent "virtual" transmit antennas.…”

This paper investigates the outage probability of the multiuser transmit antenna selection/maximal-ratio combining (TAS/MRC) system over Rayleigh fading channels with outdated feedback. The exact outage probability is first derived. Then the asymptotic outage probability is analyzed to gain more insights into the effect of feedback delay. The analytical results show that: 1) increasing the number of users has the same effect on the outage probability as increasing the number of transmit antennas at the base station; 2) with outdated feedback, the asymptotic diversity order of the multiuser TAS/MRC system reduces to the number of receive antennas at the users. Theoretical analysis is verified by simulation results.

SUMMARYMultiuser diversity (MUD) cooperative wireless networks combine the features of the MIMO systems without confronting the physical layer constraints by providing multiple copies of the transmitted signal from the source to the destination with the help of the relay node. Cooperative wireless networks have attracted the full attention in the last few years and are implemented widely in many wireless communication systems to adapt for the fading impairments, provide higher data rates, and improve the performance of the wireless communication systems. In this paper, we present an informative study for the reason of evaluating the performance of the MUD in the multiuser two‐hop cooperative multi‐relay networks using maximal ratio combining. Furthermore, we derive tight closed‐form expressions of outage probability and symbol error probability for the amplify‐and‐forward and fixed decode‐and‐forward protocols with the MUD. Additionally, we conduct a simulation study to show to what extent our analytical and simulation results agree with each other. It is worthy to mention that our analytical and simulation results agree fairly with each other under high average signal‐to‐noise ratio, whereas they show that our proposed system with multiple relays provides significant improvements over those previously proposed systems having only one relay.

This paper presents unified formulas of the outage probability and the bit error rate (BER) for multiuser diversity with different multiple‐input multiple‐output (MIMO) schemes, including (1) transmit selective/receive selective (SC/SC); (2) transmit selective/receive maximum ratio combining (SC/MRC); and (3) space–time block codes (STBC) on Nakagami‐m fading channels. The exact closed‐form expressions can be derived for the outage probability with arbitrary m and for the BER with integer m. For a non‐integer fading parameter, the BER is expressible as a single infinite series of Gamma function. We also achieve simplified calculations for the performance at high SNR to gain insights regarding the factors determining the performance in fading. It is shown that the multiuser MIMO systems can achieve a full diversity order. The achieved results provide an analytical framework for the assessment of multiuser MIMO systems. All the analytical results are verified by Monte Carlo simulations. Copyright © 2010 John Wiley & Sons, Ltd.
