“…In addition, transmission with only one antenna can eliminate practical issues such as mutual coupling, spatial correlation of antennas, and inaccurate time synchronization between antennas [22]. In the single AS scheme, K t = 1 and the ZF detector is similar to the SIC detector.…”

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.

“…MIMO systems offer dramatic data throughput gains over SIMO systems [4], and their basic properties and advantages have been thoroughly investigated by many authors. It has been shown that the incident field and the far field of the diversity antenna obey an orthogonality relationship, and the role of mutual coupling is central [5], while comparisons between spatial multiplexing schemes (SM) and diversity schemes via simulations revealed 6-12 dB higher SNR for diversity-based schemes, and 30-100% higher capacity for SM-based schemes [6].…”

-A polarisation diversity combing scheme for dualpolarised Multiple-Input and Multiple-Output channels in small cell environments introduced and evaluated. The scheme is based on post analysis of channel measurement data captured from scenarios and includes indoor-to-indoor, indoor-to-outdoor, and indoor-outdoorindoor propagation. An analysis of link signal strength and correlation with respect to frequency and polarisation revealed profound differences between co-polarised and cross-polarised links in terms of received signal strength and correlation between frequencies. Utilising these differences, a polarisation diversity combing scheme is evaluated which is shown to produce an average of 10.6dB polarisation diversity gain.

“…single user) multi-input, multioutput (MIMO) links potentially can provide diversity and array gains for increased robustness as well as multiplexing gains for increased rate via appropriate space-time-frequency codes that map information symbols to frequency-time and antennas [13][14] [15]. However, in the presence of multiple access interference (MAI) in a spatial reuse scenario [6] [5], some degrees of MIMO design choice should be allocated to suppression of co-channel interference for higher link spectral efficiency [10]. Clearly, this implies a trade-off: transmit beamforming for downlink is used to mitigate the strong cochannel interferers at the reference receiver, thereby preserving a (nearly) interference-free link for the reference pair.…”

In this paper, we consider a multicell MIMO-OFDM TDD system where the emphasis is on the downlink for future dataintensive applications. We propose a MIMO scheme that can effectively combat co-channel interference with only local BS coordination and retain the high peak rate achievable for point-to-point single-cell communications. We describe several different levels of CSI availability at both the transmitter and the receiver that lead to different system architecture choices. The performance of rate-1 SFBC code developed in [1] with channel estimation is investigated via simulation; our results show that with pragmatic channel estimation schemes, multi-cell MIMO-OFDM is a good candidate for future high-rate applications.
