- W180305720 abstract "Models of the propagation channel of Time-Modulated Ultra-wideband (TM-UWB)RF transmissions were developed using a specially built receiver with two independent receive channels. One channel was used to track the incoming signal,demodulate data,and collect statistics on a bit error test pattern of length 32768. The second channel synchronized with the first channel and scanned through time to obtain a time domain representation of the incoming waveform. This scanned waveform is representative of the actual distortion of the transmitted Gaussian waveform after being filtered by the environment.Simple statistics such as I/Rn path loss as a function of distance in several test environments are discussed. This paper also characterizes the delay spread and shows performance gain as a function of the number of correlators in the system. The optimal relative placement in time of multiple correlators,and the marginal energy gained by adding more correlators are discussed.KeywordsPath LossReceive PowerIncoming SignalDelay SpreadPower Correction FactorThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves." @default.
