Summary:
This paper1 present an interference suppression using subband adaptive array (SBAA) for space-time block coding (STBC) with multiple input multiple output (MIMO) multirate multicode code division multiple access (CDMA) under the frequency selective fading (FSF). The proposed scheme has a flexible configuration which allows base station (BS) to dynamically adapt to multirate transmission requests from mobile stations (MS). At the receiver, the received signal undergoes STBC based subband adaptive array processing at each subband to suppress the intersymbol interference (ISI), multicode interference (MCI) and multiple access interference (MAI) simultaneously. The proposed system is simulated under different channel conditions and is compared against conventional SBAA.
