Space-time block coding for wireless communications: performance results

We document the performance of space–time block codes [13], [14], which provide a new paradigm for transmission over Rayleigh fading channels using multiple transmit antennas. Data is encoded using a space–time block code, and the encoded data is split into n streams which are simultaneously transmitted using n transmit antennas. The received signal at each receive antenna is a linear superposi...

Extended balanced space-time block coding for wireless communications

Diversity techniques are very effective tools to increase signal reception quality in Rayleigh fading channels. A well-known method to increase diversity in multi-input multi-output (MIMO) communication is transmit antenna selection (TAS). However, TAS is very sensitive to feedback errors. One of the alternative techniques to TAS is balanced space-time block coding (BSTBC) which guarantees full...

Channel estimation for wireless communications using space-time block coding techniques

This paper presents a method of estimating channel parameters in wireless communications using space-time block coding (STBC). After reviewing the concept of STBC, the system model of radio communication with STBC is described and the estimation method is derived. System performances have been simulated using MATLAB. The results of the simulations show that the proposed algorithm of channel est...

Combined Beamforming and Space-Time Block Coding for High Speed Wireless Indoor Communications

The combination of a digital beamforming technique with space-time block coding in an indoor wireless environment is the purpose of this paper. Uplink transmission is achieved by an omnidirectional mobile antenna, with signals arriving at the base station having relatively wide angular spread. The spatial channel response, an estimate of the channel angular gain pattern, is obtained by using an...
