High speed bit error rate estimation in frequency selective time-varying channels

Over the gears many wideband propagation modelling techniques have been proposed for indoor and microcellular environments. However, obtaining system quality of service information is still a time consuming process that often requires extensive computer simulation. In this paper a unique technique is presented that rapidly estimates the average and instantaneous bit error rate for frequency selective time-varying channels. The method was developed to process the wideband channel impulse response information generated by the latest ray-tracing propagation models. The technique combines the speed associated with a theoretical investigation with the flexibility of a conventional simulation. To confirm the accuracy of our algorithm, both the instantaneous and average bit error rates for coherent PSK are estimated and compared with results obtained by previous authors.<
