EFFICIENCY OF SPACE-TIME BLOCK CODING IN INDOOR ENVIRONMENT

Popis výsledku v původním jazyce

Space-time coding is new technique using joint of transmit diversity and coding. Space-time codes provide both diversity and coding gain when using multiple transmit antennas to increase spectral efficiency over wireless communications systems. Alamouti's simple two-branch transmit diversity scheme is adopted [1]. Alamouti's scheme was originally designed for flat (frequency non-selective) fading channels, but the condition for frequency selectivity is not defined exactly. The efficiency of space-timeeblock coding in frequency selective and non-selective fading channels is compared. Quasi-static Rayleigh fading channels in indoor environment are assumed. This paper presents a large effect of frequency selectivity on the space-time communication system. These results are useful for BER vs. bit rate performance evaluation of the indoor radio communication systems.
