Abstract

New channel simulation models are needed for the study of future wireless networks, 5G and beyond. A novel simulation technique dubbed weighted-counting is proposed. It is used to generate random variates having the two-wave with diffuse power (TWDP) fading amplitude distribution. The TWDP channel model describes high-speed train, femtocell, sea surface, heterogeneous, and other channels having two different dominant line-of-sight waves as well as scatter power components.

Highlights

  • T HE two-wave with diffuse power (TWDP) fading model is an important model for present and future wireless communication systems [1]- [7]

  • The contributions of this letter are first, to propose a novel simulation method dubbed, “weighted counting”, and second to study how the weighted counting method can be used to simulate the amplitude of two-wave with diffuse power (TWDP) fading channels

  • We have found empirically that there are no problems in simulating values of K ≤ 12 dB
