On the Multipath Propagation Modeling Based on Ray Optical Approach

摘要

A signal design method using complete complementary codes has been proposed. This method is based upon the estimation of the multipath channels and the convolution of spread-time signals. Modeling the multipath propagation is essentially required to evaluate the efficiency of this method. In this paper, we describe the well-known wave propagation modeling based upon the ray optical method, and discuss the way to improve its accuracy.
