UWB_Rake_Receiver_Correlator

The correlator multiplies the receive signal with a reference signal and integrates the results over a period of time. The integrator in the correlator integrates the multiplier output signal over the period of ChipInterval×ChipsPerBit. It resets the integrator value to 0 and restarts the integration.

UWB_RX_SINGLE_FINGER_CORRELATOR has a single finger path; UWB_Rake_Receiver_Correlator has 4 finger paths.

Name	Description	Default	Unit	Type	Range
ChipsPerBit	Number of pulses transmitted for each bit.	1		Integer	>1
ChipInterval	Time between pulses.	1 nsec	Time	Real	>0
