Abstract
In this paper, we propose the space-time joint detection scheme with the new directional channel impulse response (DCIR) estimation in TD-SCDMA uplink with antenna array. The new DCIR estimation applied to the beamforming concept, is the combined scheme in which we obtain the channel impulse response (CIR) estimate and the array response vector estimate for each path of all users, respectively. Compared to the space-time joint detection with the conventional DCIR estimation, the new estimation scheme offers a considerable performance improvement, and this is very attractive to implement easily because of the low computational complexity.
