In the flat Rayleigh fading channel,MISO quasi orthogonal space-time code for 8 antenna system was introduced.Instantaneous signal-to-noise ratio of eight antennas quasi orthogonal space-time code was derived according to ABBA2.Then Monte Carlo simulation results showed: channel capacity was increased with the increase of antenna in antenna power normalization conditions for the full rate of orthogonal space-time code,but for large number of antenna,its capacity to improve was not obvious.While receiving antennas were increasing,the capacity of the system was improved greatly.
