Signals are aligned in phase andd combined at RF stage to avoid deep fades and reduce the hardware cost of RF to baseband conversion. Gradient-based adaptive algorithms are implemented on a TI320C30 DSP processor. Space-Time processing can assure that spatial and temporal diversity are fully captured. Research emphasis on exploring diversity gain of different basestation antenna topologies, reducing received signal variation and thus improve power control accuracy in CDMA, and reducing power budget. Research emphasis on channel estimation, energy distribution among antennas, adaptive antenna weight adjustment and fading compensation.
Performance improvement is verified by simulations.
