Dual-Domain Transform for Travelling Wave in FRFT Domain

In wireless communication, the travelling electromagnetic (EM) wave nature of the signal is not reported comprehensively in the literature. To date, the majority of reported work analyzed the nature of the signal propagating through the channel in time and frequency domains only, whereas the travelling EM wave which is actually propagating through the channel, has both time and spatial dependencies. Very little work has been reported in which this aspect of EM wave is being analyzed, but the time dependency of frequency and spatial dependency of propagation constant associated with the EM wave have not been included, which will affect the performance of the channel in practical conditions. In this paper, all these aspects of EM wave and channel are considered to define a new method (DDT-FRFT) to analyze the travelling EM wave for wireless communication.
