Abstract(in English) | We have been studied the implementation of fast DOA (Direction of Arrival) estimator called UMP (Unitary MUSIC Processor) using dedicated circuit device of FPGA (Field Programmable Gate Array). This paper presents the estimation accuracy of the UMP and proposes a practical uplink smart antenna system based on DOA estimation with UMP. This system steers the main-lobe for user direction and low side-lobe for the other directions with the modified version of Dolph-Chevyshev beampattern with simple bit shift-add operation to implement easily on logic devices like FPGAs. This paper also shows that it has reasonable performance for the other techniques that require heavy computational load. The total performance evaluation under the multi-path fading channel with small angle spread was analyzed through the hardware level fixed point simulation of UMP DOA estimator. |
