Abstract—Atime-domain noise model is developed for analyzing the performance Pvbw
>k;  
degradation of wireless communication systems in the 2.4-GHz 2S!=2u+7  
band caused by microwave ovens, taking into account the noise generation ,ZMYCl]  
mechanism and its characteristics. The proposed noise model consists of BN#^ /a-  
a series of frequency-modulated tone bursts, which can be realized with a &(Xp_3PO  
set of FM/AM modulators. It yields a simple and general expression of the  "thfd"-  
noise waveform in terms of six parameters that can be determined from a`/[\K6  
measurements. Band-limited noise waveforms can also be derived from the f4@Dn >BJ  
model via simple approximations. Comparisons of both the waveform and G=yQYsC$  
the frequency spectrum are made between actual noises and the proposed #cjB <APY  
model, which clearly demonstrate the validity and usefulness of the model. ;qG a|`#j
