| Rayleigh fading model is the most common model to describe the fading experienced by the radio signal in cities. In the first part of this paper, the statistical model for Rayleigh fading is presented, as well as the further classification of Rayleigh fading based on the parameter characteristics, with emphasis on frequency-selective fading and its usual mitigation methods. In the second part the mitigation method adopted in IS-95 CDMA: RAKE receiver, is introduced. Then, an example of 2-branch RAKE receiver is illustrated to show the advantage of RAKE receiver, together with equal gain combination technique which is one of the common three combination techniques used in IS-95. |
