“…Digital communication using MIMO wireless link, has recently emerged as one of the most significant technical breakthroughs in modern communications such as IEEE 802. 16 WiMax, IEEE 802.11 WiFi, cellular third and forth generation (3G/4G) systems [11]. Hence, for high data rate, multiple antenna structure is assumed here.…”

In this paper, delay constrained performance of a multiple-input multiple-output (MIMO) communication system in a dense environment with co-channel interference is investigated. We apply orthogonal space-time block coding (OSTBC) at the transmitter, and for alleviating the high complexity and cost of the MIMO system, receive antenna selection (RAS) scheme is employed in the downlink. Here, for simple and cheap mobile handsets, one antenna is chosen at the receiver in each utilization of the channel. Under these assumptions, a maximum constant arrival rate with the delay qualityof-service (QoS) guarantee in a wireless channel is extracted. We obtain a closed-form solution for the effective capacity of the MIMO-OSTBC channel with the RAS scheme in a quasi-static Rayleigh fading conditions and cochannel interference. After all, the numerical simulations are provided and verified the theoretical results.

“…However, the multiple-antenna front-end architecture design traditionally results in greater complexity and higher hardware costs in the radio frequency (RF) section [4,5]. One simplifying and cost-reducing solution may be the utilization of a single RF front-end, where a single RF path is used instead of multiple parallel RF chains [4,5]. In addition, the antenna selection (AS) technique is a common method for dealing with this issue [6][7][8][9][10].…”

Abstract:In this paper, a new throughput-based transmit antenna selection (AS) scheme is evaluated. First, a closedform solution for the throughput rate of a multiple-input multiple-output (MIMO) system, with a truncated selective repeat automatic repeat request (TSR-ARQ) or selective repeat plus go-back-N automatic repeat request (SR+GBN-ARQ) protocol at the data link layer, is proposed. In addition, a throughput-based AS technique with adaptive modulation is also investigated. For this purpose, the throughput and packet error rates of a MIMO system with a transmit AS and TSR-ARQ protocol at the data link layer are analyzed. This study is conducted in 2 different cases.In the single-transmit AS case, the probability density functions (PDFs) of the throughput and packet error rates at the data link layer are derived. Moreover, in the case with multiple-transmit AS, a lower bound for the throughput rate and an upper bound for the packet error rate at the data link layer are determined. Consequently, the PDFs of these lower and upper bounds are extracted.

“…In addition to self-interference cancellation, the antenna selection can also simplify and reduce the volume and power consumption of the RF section in both transmitter and receiver [16]. Hence, the use of this method is very common in multi-antenna communication systems.…”

The use of full-duplex (FD) communication systems is a new way to increase spectral efficiency. For this reason, it has received serious attention in the new generation of wireless communication systems. The main challenge of FD systems is self-interference that needs to be reduced appropriately. In this paper, we have considered an FD multi-antenna base station in a cellular network and we have used the antenna selection technique to resolve the self-interference issue. We have also provided a new criterion to select an appropriate antenna. In this new criterion, the antenna selection is modeled as a multi-objective optimization problem. Here, the antennas which simultaneously minimizes interference channel gain and maximizes uplink (UL) and downlink (DL) channel gains are selected for transmission and reception. The base station has to perform well in both the UL and DL and reduce the self-interference simultaneously. Therefore, the multi-objective criterion has a better performance than the single-objective criterion. Although, in conventional antenna selection with the single-objective criterion, only the function of the UL and DL channels or the interference channel is considered. Finally, the simulations show that the new criterion has a higher throughput rate than the other conventional single-objective antenna selection techniques.
