Multipath Simulation without Radio Frequency Delay Devices.

Abstract

A new technique for multipath simulation that does not require RF delay devices is presented. It is shown that the delays associated with multipath can be achieved at baseband (data) frequencis and the effect transferred to the RF signal. The technique can be applied to all forms of RF modulation (FM, PM, AM) and all baseband formats (PCM, PAM, FM/FM, etc.). Any number of indirect paths can be simulated. The effects arising from motion of the transmitter and/or receiver for a given flight configuration can be simulated. Diversity signals including multipath effects can be simulated. Methods for implementing these techniques are presented. (Author)
