Abstract: Based on the typical channel model of STBC in MIMO (multiple-in, multiple-out) wireless communication channels, a general expression of instantaneously received signal-noise ratio and anti-noise performance of OSTBC(orthogonal space-time block codes) over Rayleigh fading channel is deduced. A simulation was conducted using Simulink, as a result, the BER(bit-error rate) of several STBC systems modulated differently are comparatively analyzed. The results showed that when the number of receiving antennas is fixed, the performance of OSTBC is improved with the increasing number of transmitting antennas, and the more the number of transmitting antennas, the less the improvement. It is also revealed that the bandwidth utilization ratio is in complementary relation to anti-noise performance.
