A new technique for derivation of LCR and AFD in wideband wireless channel
A new technique to derive level crossing rate (LCR) and average fade duration (AFD) in a wideband wireless communication channel is proposed. The analytical formulation of LCR and AFD is based upon the channel impulse response and the consequent tapped-delay line structure. As the statistics of the received multipath signal changes from one delay bin to another, statistical quantities like LCR and complimentary distribution function (CDF) are calculated separately at each delay bin and then they are combined by proper weights to obtain the overall LCR and AFD of the signal. Results are shown for two cases of multipath propagation channel - single cluster and multi-cluster.
