Statistical model of microwave oven interference and optimum reception

Abstract

Microwave oven interference seriously degrades the performance of digital radio communication systems, therefore, in order to obtain a good error performance under a microwave oven interference environment, the digital radio communication systems should be newly designed for this environment. In this paper, using the Middleton's (1977) canonical class-A impulsive noise model, we propose a statistical model of microwave oven interference and discuss the performance improvement achieved by optimum reception based on this statistical model. Numerical results conclude that the first order statistics of microwave oven interference can be modeled by class-A impulsive radio noise, and a great performance improvement is obtained by using the optimum receiver designed against microwave oven interference with the introduction of the sample interleave scheme.
