Since the publication of Alamouti’s famous space-time block code for two transmit antennas, various suboptimal space-time block codes for multi-input/multi-output fading channels have been proposed not achieving full diversity at full rate. In this paper we present a family of adaptive, channel dependent, rate-one Extended Alamouti spacetime block codes for four and eight transmit antennas. Onl...

Clustering ensemble performance is affected by two main factors: diversity and quality. Selection of a subset of available ensemble members based on diversity and quality often leads to a more accurate ensemble solution. However, there is not a certain relationship between diversity and quality in selection of subset of ensemble members. This paper proposes the Hierarchical Cluster Ensemble Sel...

Abstract SPACE-time coding is a transmit diversity scheme with optional receive diversity to achieve high data rate and to improve the reliability of a wireless channel. In the past, STBC has full rate and full diversity for four transmit antennas. This technique has high cost and high complexity due to the more feedback information. In this paper, feedback-rotated QOSTBC technique is used to i...

The 2 × 2 MIMO profiles included in Mobile Wi-MAX specifications are Alamouti’s space-time block code (STBC) for transmit diversity and spatial multiplexing (SM). The former has full diversity and the latter has full rate, but neither of them has both of these desired features. An alternative 2×2 STBC, which is both full rate and full diversity, is the Golden code. It is the best known 2×2 STBC...

Multi-antenna systems allow for a significant increase in the transmission rate of coherent wireless transmissions over flat Rayleigh fading channels. Various multi-antenna designs have been developed in recent years targeting either high-performance, or, high rate. In this paper, we design a layered space-time (ST) scheme equipped with linear complex field (LCF) coding, which enables full dive...

In multiple-input multiple-output (MIMO) fading channels, the design criterion for full-diversity space-time block codes (STBCs) is primarily determined by the decoding method at the receiver. Although constructions of STBCs have predominantly matched the maximum-likelihood (ML) decoder, design criteria and constructions of full-diversity STBCs have also been reported for low-complexity linear ...

Space-time coding for the flat fading, quasistatic MIMO wireless channel has received wide spread attention. This paper treats space-time code design for frequency selective channels from a single carrier modulation perspective. We present a general framework for analyzing space-time codes for delay spread channels based on PEP analysis. It is shown that as in the flat fading case, diversity ga...

This paper proposes a class of full space diversity QPSK space-time codes based on parallel concatenated convolutional (turbo) codes. A rank criterion of full space diversity is used in the design. Compared with space-time trellis codes, the simulations show it has robust performance at both quasi-static fading channel and time varying fading channel.

Abstract—Partial interference cancellation (PIC) group decoding proposed by Guo and Xia is an attractive low-complexity alternative to the optimal processing for multiple-input multipleoutput (MIMO) wireless communications. It can well deal with the tradeoff among rate, diversity and complexity of spacetime block codes (STBC). In this paper, a systematic design of full-diversity STBC with low-c...
