Abstract-It is now well known that employing channel adaptive signaling in wireless communication systems can yield large improvements in almost any performance metric. Unfortunately, many kinds of channel adaptive techniques have been deemed impractical in the past because of the problem of obtaining channel knowledge at the transmitter. The transmitter in many systems (such as those using frequency division duplexing) can not leverage techniques such as training to obtain channel state information. Over the last few years, research has repeatedly shown that allowing the receiver to send a small number of information bits about the channel conditions to the transmitter can allow near optimal channel adaptation. These practical systems, which are commonly referred to as limited or finite-rate feedback systems, supply benefits nearly identical to unrealizable perfect transmitter channel knowledge systems when they are judiciously designed. In this tutorial, we provide a broad look at the field of limited feedback wireless communications. We review work in systems using various combinations of single antenna, multiple antenna, narrowband, broadband, single-user, and multiuser technology. We also provide a synopsis of the role of limited feedback in the standardization of next generation wireless systems.

“…In the conventional receive antenna selection for the orthogonal STBC (O-STBC) with full diversity, the receiver computes SNRs for every receive antenna and select one with the maximum SNR [10]. For the QO-STBC, the optimum criterion was proposed to trade off a maximization of the channel gain with a maximization of the channel dependent interference parameter when ZF decoder was considered [11]. Here, EO-STBC is the one of non-orthogonal STBCs.…”

Complex orthogonal space-time block codes (ST-BCs) with linear processing for more than two transmit antennas can not achieve a full rate in multiple-input and multiple-output (MIMO) channels. However, at the expense of loosing some degree of diversity advantage, it is possible to achieve a full rate or even rates higher than one for any number of transmit antennas. In this paper, we propose new closed-loop extended orthogonal STBCs (EO-STBCs) for three and four transmit antennas. We show that the schemes can achieve a full transmit diversity with linear processing and they outperform the previous closed-loop STBCs. In addition, we investigate the closed-loop EO-STBCs with receive antenna selection. It is shown that for four transmit antennas and up to three receive antennas, performance gains of up to 5.8 dB are obtained over the closed-loop EO-STBCs without antenna selection. The performance improvement is also investigated when the proposed method is concatenated with bitinterleaved turbo coded modulation (BITCM).

“…Though the DSTTD scheme outperfonns general MIMO schemes, still the perfonnance can be further improved by using Receive Antenna Selection (RAS) scheme [5][6][7][8][9]. The Southeast University, 210096 Nanjing, China juliu@sdu.edu.cn idea of antenna selection is based on the scenario that as the hardware configuration of the MIMO systems is difficult to remodel, we can install a larger set of antennas and allot RF chains to the best antenna subset combination by utilizing lowcost RF switches.…”

The Double Space Time Transmit Diversity (DSTTD) system was proposed to obtain both transmit diversity gain and spatial multiplexing gain simultaneously. The DSTTD scheme outperforms general Multiple Input Multiple Output (MIMO) scheme, however the performance can be enhanced by using Receive Antenna Selection (RAS) scheme and Transmit Antenna Shuffling (TAS) scheme. In this paper, we realized the RAS algorithm for DSTTD system using Integer Programming (lP), which is aims to minimize the system Bit-Error Rate (BER). Combined with TAS scheme, the transmit antennas of the DSTTD systems are grouped according to the shuffling pattern information fed back by the receiver. Also, the integer programming algorithm can be used in choosing the shuffling pattern. By this way, the performance of the DSTTD systems can be strengthened further. As the results show, the system capability achieves further improvement with limited information redundancy.
