Abstract :
Combining coding, modulation, transmit and receive diversity, and validly increases the anti-noise performance in fading channels, OSTBC (orthogonal space-time block codes) is a new channel coding technology accompanying with the extensive application of wireless communication. Based on typical channel model of the OSTBC in MIMO (multiple-in, multiple-out) wireless communication channels, a general expression of instant output SNR(signal-to-noise ratio ) and anti-noise performance for OSTBC over quasi-static flat Rayleigh fading channel is deduced, and the simulation and the comparison and analysis of the BER(bit-error rate) results are implemented on several OSTBC systems, based on different modulations using Simulink.
