| Abstract(in English) | A cooperative signal reception and down-link beam forming algorithm is proposed for mobile communication systems employing phase-shift-keying (PSK) modulation. Down-link beam optimality is defined as maximizing the desired reference user's average received power while keeping the noise power plus tptal amount of average powers received by other users less than or equal to a certain constant level. The proposed algorithm nequires neither the detection of other user's signals nor knowledge about the direction-of-arrival (DOA)'s of the incident path components. Results of a series of exhaustive simulations are presented to demonstrate the overall performance of the proposed algorithm. For a hexagonal cell layout, the distribution of signal-to-interference powerratio (SIR) in a reference (central) cell with the optimal down-link beem is evaluated and compared with that with a unit gain omni-directional antenna through computer simulations fbr an 8-element circular array. The beam forming performances are also evaluated under several sets of practical parameter values with regard to the fading correlation. |
