A zero-forcing (ZF) equalization criterion is developed for a dual antenna receiver on the forward link in a CDMA based multi-user communication system. In the forward link, all users are broadcasted synchronously and the multi-user access interference (MAI) traverses the same channel as the desired user. Thus, effecting ZF equalisation (with two antennas) for the desired user also also effects ZF equalization for the MAI. Assuming the use of orthogonal variable spreading factor (OSVF) codes on… CONTINUE READING
