Joint linear multi-sensor reception in downlink TD/CDMA

In downlink TD/CDMA multiple access scheme through a multipath channel, the use of short complex codes permits the use of a strategy of joint detection. In this paper, we first use the Cross-spectral Matrix of the aliased coded channels to recall expressions and performances of Zero-Forcing linear multi-user detector through a selective channel, with or without fading. Average INSR and Bit Error Probability are then computed in indoor and pedestrian channel environments in order to show the great benefit of one or two supplementary sensors at the reception. We also describe a channel estimation method and its complexity.
