FPGA Implementation of Isotropic and Nonisotropic Fading Channels

A realistic fading channel simulator (FCS) is a key component for the development and faithful performance evaluation of wireless communication systems. This brief presents an efficient implementation of an FCS on a single field-programmable gate array. The FCS utilizes a configurable filter processor along with a multistage interpolator for a compact implementation. The FCS can be parameterized to accurately reproduce the statistical properties of both isotropic and nonisotropic scattering scenarios.
