In this paper, we investigate the performance of a decoupled space-time processing technique in a TDMA cellular system. This structure has, as its main characteristic, the possibility of giving more degrees of freedom to an antenna array, and it can thereby provide better co-channel interference cancellation. We analyze its performance by link-level simulations and its sensitivity for parameters like delay spread, path angle separation and signal-to-interference ratio. The results show that the

... decoupled space-time structure can outperform the conventional linear space-time structure, especially in cases with a high level of CO-channel interference.
