Performance analysis of STBCs for mobile wireless systems [articol]

Abstract

The main goals in developing new wireless communication systems are increasing the transmission capacity and improving the spectrum efficiency. Spacetime block coding (STBC) exploit the richly scattered wireless channel by transmitting redundant data streams from multiple antennas in order to improve the reliability of data transfer and greatly increase data transmission rates without additional radio resource requirements. Significant performance gain is achieved by varying some transmit parameters at almost no processing expense, while a simple, linear maximum decoding algorithm operates at the receiver.
