Charalambous chadcha@ Received 3 December 2007 Revised 30 March 2008 Accepted 22 July 2008 Recommended by Xueshi Yang This paper provides a connection between the shot-noise analysis of Rice and the statistical analysis of multipath fading wireless channels when the received signals are a low-pass signal and a bandpass signal. Under certain conditions explicit expressions are obtained for autocorrelation functions power spectral densities and moment-generating functions. In addition a central limit theorem is derived identifying the mean and covariance of the received signals which is a generalization of Campbell s theorem. The results are easily applicable to transmitted signals which are random and to CDMA signals. Copyright 2008 Charalambos D. Charalambous et al.

INTRODUCTION A statistical temporal model which captures the time-varying and time-spreading properties of the channel is the so-called multipath fading channel model MFC 1 pages 12 13 760 761 2 page 146 3 .
