In this paper, we propose a new full-rate, full-diversity STBC for the quasi-static Rayleigh flat fading 2times2 MIMO channel. This code has an ML-decoding complexity of the order of M3. For square QAM, the ML-decoding complexity is of the order of M2radic2. and also matches the Golden code in coding gain for 4- and -16 QAM constellations, and have the non-vanishing determinant (NVD) property for...
Distributed wireless communication system has been considered as a promising architecture for future wireless communication networks. This paper aims to characterize the power allocation scheme for orthogonal space time block coding in DWCS. Firstly, an optimal method is investigated, which minimizes the upper bound of the ergodic pair-wise symbol error rate, and it is proved to be equivalent to waterfilling...
Hybrid MIMO scheme applies some of the transmit antennas with pure diversity schemes (e.g. STBC) while others with pure spatial multiplexing schemes (e.g. VBLAST), in order to achieve the diversity gain and multiplexing gain at the same time. However, the spatial multiplexing schemes without diversity gain are susceptible to the fading effect. In this paper, we propose an adaptive hybrid MIMO scheme...
The combination of spatial division multiplexing (SDM) and space-time block coding (STBC) is able to yield high-throughput and robust wireless communications (e.g. IEEE 802.11n). In the most common configuration, known as double space time transmit diversity (DSTTD), two Alamouti encoded streams are transmitted in parallel. In this paper we introduce an improved multicarrier hybrid STBC/SDM scheme...
