Abstract
A novel receiver for space-time coded systems based on the reduced rank multistage Wiener filter (MWF) is presented. It is shown that this receiver has a complexity that is only a linear function of the processing gain (N), the number of transmit antennas (Lt ), and the rank (D) of the MWF. The complexity of the equivalent MMSE solution is a function of (N Lt )3. It is also demonstrated by numerical simulation that this receiver meets MMSE performance at a significantly lower rank. The MMSE implementation is derived and performance is evaluated for highly loaded synchronous CDMA systems in flat fading.
