Throughput of CSMA in a Rice-signal with Hoyt-interference environment

Abstract

This paper investigates the throughput performance of carrier sense multiple access (CSMA) with the desired signal modelled by the Rice distribution and the interference following the Hoyt distribution (in this paper denoted as combined Rice and Hoyt fading channel). The approach considered here assumes that the desired signal includes a dominant component and thus may be modelled using the Rice distribution. In addition, the Hoyt distribution is used for the interference signal since it is assumed that in this case no dominant signal is present and the variances of the in-phase and quadrature components of the received signal are different or correlated. Also, the approach considered includes the signal capture model with coherent and incoherent addition of interfering signals and uniform attenuation for all terminals (or perfect power control). The formulations derived here are exact and unprecedented in the literature.
