Summary:
Correlation coefficient is a important parameter that indicates the efficiency of correlation receiver for Ultra Wideband Impulse Radio (UWB-IR) systems. The correlation coefficient is also used to analyze the waveform distortion. In this paper, the closed form formulas of correlation coefficient are derived using the rectangular passband waveform and the extension of Friss’ transmission formula. The free space and ground reflection channels are considered. The results obtained from proposed formulas are compared with measurement. For ground reflection channel, the proposed formula of correlation efficient corresponds with measurement.
