MultipathDelayBlock_UWB_Channel

Delay inputs are the incremental delays from one multi-path input to the next. Relative magnitudes of each arrival are applied. Multi-path delay blocks can be connected in series to produce as many arrival times as required. Series connection uses Single Delayed Output pin 2. Delay1 through Delay5 and Mag0 through Mag4 affect the delay paths; when one MultipathDelayBlock_UWB_Channel is used, set Delay6=1 and Mag5=1, and connect as in UWB_ENVIRONMENT. For low pulse-rate applications where arrivals of sequential pulses do not overlap, it may be necessary to include arrivals within the integration window of the receiver correlators only.

Note Multipath terms can be defined using the IEEE P802.15.3 SG3a study group standard model based on a model developed by Saleh and Valenzuela (S-V) which includes a log-normal decay of the clusters along with a log-normal decay of rays within each cluster. See the SG3A "Channel Modeling Sub-committee Report (Final)," IEEE P802.15-02/490r0-SG3a, December 2002.
