Abstract :
In this paper, we first analyze the amount of fading (AF) of orthogonal space-time block codes (STBCs) over spatially uncorrelated keyhole channels. In order to investigate the diversity order of keyhole channels, we then derive an approximate expression for the average bit error rate (BER) at high signal-to-noise ratio (SNR). Finally we present the average capacity expression by applying the Gauss-Laguerre integration.
