Weighted Non-coherent Energy Detection Receiver for UWB OOK Systems
Non-coherent energy detection receiver is an attractive solution for impulse radio ultra-wideband (IR-UWB) systems due to the low implementation complexity.In this paper,we propose a novel weighted non-coherent energy detection receiver for on-off keying (OOK) UWB systems in multi-path environment.The performance of this receiver is improved by weighting the subinterval integrator output with a function related to the channel energy delay profile.Signal subintervals with larger energy contributions are given larger weights,thus improving the receive signal-to-noise (SNR).The error probability of proposed receiver is analyzed,and its superiority over the conventional one is examined by numerical results using IEEE 802.15.4a channel model.
