ICA based blind detection scheme in space-time block coding communications
Tongxin xuebao, 2007 Space-time block coding（STBC） schemes are capable of improving system performance by using transmit diversity strategy and specific coding schemes.Nevertheless,they need precise channel state information（CSI） at the receiver end in order to achieve good ...

Adaptive transmit eigenbeamforming with orthogonal space-time block coding in correlated space-time channels [PDF]
, 2004 Conventional space-time codes can provide a significant improvement in system performance only if the signal paths are spatially uncorrelated, a condition that is hardly met in practice.

Autocorrelation based channel estimation method for space-time block coding system
Tongxin xuebao, 2007 An autocorrelation based method was proposed to estimate the channel of the space-time block coding（STBC） system.It is shown that when the inputted symbol vector is spatially white,the autocorrelation of the received signal has specific structure due to ...

, 2001 Prior treatments of space-time communications in Rayleigh flat fading generally assume that channel coding covers either one fading interval-in which case there is a nonzero “outage capacity”-or multiple fading intervals-in which case there is a nonzero ...

PERFORMANCE ANALYSIS OF MIMO-SPACE TIME BLOCK CODING WITH DIFFERENT MODULATION TECHNIQUES [PDF]
ICTACT Journal on Communication Technology, 2012 MIMO Diversity is the technique which takes the advantage of multipath and mitigates the effect of fading and increases signal strength. Space Time Block code (STBC) is used in Multiple Input Multiple Output (MIMO) system to improve the performance by ...

Space-Time Block Coding with Beamforming for Triple-Polarized Uniform Linear Array Systems
International Journal of Antennas and Propagation, 2015 Generally, space-time block coding (STBC) and beamforming (BF) gains cannot be obtained simultaneously because the former performs well under a low correlated MIMO channel, and the latter works efficiently in an environment with high correlation. However,

Censored Distributed Space-Time Coding for Wireless Sensor Networks
EURASIP Journal on Advances in Signal Processing, 2007 We consider the application of distributed space-time coding in wireless sensor networks (WSNs). In particular, sensors use a common noncoherent distributed space-time block code (DSTBC) to forward their local decisions to the fusion center (FC) which ...

Space-time block codes versus space-frequency block codes
The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004 In wireless broadband systems the available time, frequency and spatial diversity can be exploited using complex space-time-frequency codes. However, in order to retain a flexible scheme with low complexity we prefer a concatenated system where a channel code picks up time and frequency diversity and a simple orthogonal design is used to obtain spatial
