Abstract—Atime-domain noise model is developed for analyzing the performance ;gLHSHEA  
degradation of wireless communication systems in the 2.4-GHz it.Lh'N;T  
band caused by microwave ovens, taking into account the noise generation {VtmQU?cJ  
mechanism and its characteristics. The proposed noise model consists of k&wCa<Rs~R  
a series of frequency-modulated tone bursts, which can be realized with a @E;'Ffo  
set of FM/AM modulators. It yields a simple and general expression of the {AUhF}
O  
noise waveform in terms of six parameters that can be determined from F6 ?4&h?n  
measurements. Band-limited noise waveforms can also be derived from the YRa{6*M  
model via simple approximations. Comparisons of both the waveform and @/FE!6 |O  
the frequency spectrum are made between actual noises and the proposed K4~z@. G6*  
model, which clearly demonstrate the validity and usefulness of the model. z SDRZ!
