In this paper, we propose a QR-based detection scheme of orthogonal space-time block codes for very fast fading channels. The proposed detection scheme employs a QR decomposition on the channel matrix and minimizes noise enhancement which occurs in an existing detection scheme. The performance of the proposed detection scheme is evaluated by computer simulations for various very fast fading channels. It is shown that when the channel fading is very fast, the proposed detection scheme outperforms the existing detection scheme
