A time-domain microwave oven noise model for the 2.4-GHz band

A time-domain noise model is developed for analyzing the performance degradation of wireless communication systems in the 2.4-GHz band caused by microwave ovens, taking into account the noise generation mechanism and its characteristics. The proposed noise model consists of a series of frequency-modulated tone bursts, which can be realized with a set of FM/AM modulators. It yields a simple and general expression of the noise waveform in terms of six parameters that can be determined from measurements. Band-limited noise waveforms can also be derived from the model via simple approximations. Comparisons of both the waveform and the frequency spectrum are made between actual noise and the proposed model, which clearly demonstrate the validity and usefulness of the model.
