Blind detection of orthogonal space-time block coding based on ICA schemes
Tongxin xuebao, 2006 By introducing information in both space and time domain, transmit diversity gain could be achieved by or-thogonal space-time block coding （OSTBC）, and higher coding gain could be obtained without sacrifice of bandwidth.

EURASIP Journal on Advances in Signal Processing, 2007 Distributed space-time block coding (Dis-STBC) achieves diversity through cooperative transmission among geographically dispersed nodes. In this paper, we present a power-efficient relay-selection strategy for decentralized Dis-STBC in a selective decode-

Codes over Matrix Rings for Space-Time Coded Modulations
, 2010 It is known that, for transmission over quasi-static MIMO fading channels with n transmit antennas, diversity can be obtained by using an inner fully diverse space-time block code while coding gain, derived from the determinant criterion, comes from an ...

Optimal STBC Precoding with Channel Covariance Feedback for Minimum Error Probability
EURASIP Journal on Advances in Signal Processing, 2004 This paper develops the optimal linear transformation (or precoding) of orthogonal space-time block codes (STBC) for minimizing probability of decoding error, when the channel covariance matrix is available at the transmitter.

Pragmatic Space-Time Codes for Cooperative Relaying in Block Fading Channels
EURASIP Journal on Advances in Signal Processing, 2008 We address the problem of construction of space-time codes for cooperative communications in block fading channels. More precisely, we consider a pragmatic approach based on the concatenation of convolutional codes and BPSK/QPSK modulation to obtain ...

, 2019 Wireless networks have quickly become part of everyday life. Wireless LANs, cell phone networks, and personal area networks are just a few examples of widely used wireless networks. However, wireless devices are range and data rate limited. The research community has spent a great deal of effort on finding ways to overcome these limitations. One method
