Abstract

A modified Nakagami-lognormal distribution has been proposed to represent statistical nature of land mobile satellite (LMS) channel. The normal or Gaussian variable associated with lognormal distribution is taken to be correlated with its time derivative. It does not change the probability density function but modifies the expression of level crossing rate (LCR), which is derived in this paper. The proposed model takes the conventional Nakagami-lognormal model as its special case which can be achieved by setting the correlation coefficient to zero. This correlation coefficient provides an extra degree of freedom in modeling the LMS channel. The effect of this correlation coefficient and other important parameters on LCR, computed from derived expression, has been depicted with LCR curves.
