Abstract
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.
