碩士 === 國立交通大學 === 電信研究所 === 85 === A newly developed hybrid model,composed of a two- dimensional(2-D)site-specific model and a randomly scattered model,is employed toinvestigation the Rician Factor of indoor flat fast fading channels.In our model,the averaged scattered( diffused)envelop,which has a significanteffect on the Rician Distribution and is usually neglected,can be effectivelyquantified by a ratio factor r. With a proper chosen value of r,our model yields a reasonable prediction accuracy of the Rician factor. It is foundthat a larger value of r represents a stronger scattered field and yields a small value of K,which is usually happened at the sites with heavy surroundingclutters or in NLOS(non Line-Of-Sign)propagation situations.
