Abstract :
The main focus of this presentation is adaptive down-link beam forming for PSK modulation based on subspace decomposition. A down-link beam forming algorithm with reasonable complexity is proposed which requires neither detection of other users´ signals nor knowledge about the direction-of-arrival (DOA)s of the incident path components. The desired signal subspace is extracted from the composite space in cooperation with the optimal beam forming for uplink signal reception
