UWB spatial multiplexing by multiple antennas and RAKE decorrelation

An ultra wide band (UWB) spatial multiplexing architecture employing multi-elements antennas (MEA) at the emitter side is presented and analyzed in this paper. This work evaluates the performance of the demultiplexing process at the receiver side, as ensured by multiple parallel RAKE receivers in order to achieve channel decorrelation. The quality of signal restitution, the sub-channels isolation and the quality of the communication links are evaluated by a normalized similarity coefficient, an inter-channel interferences level ratio and a bit error rate (BER) curve respectively
