Accurately modeling the channel is extremely important for the design of communication systems. Knowledge of the key features of the channel provides the designers with the ability to predict performance of the system for specific modulation, channel coding, and signal processing. In this paper, we will present the analysis of the physical properties of an UWB channel model and propose model for extremely short distance wireless communications (with a comparison to the IEEE 802.15.3a channel model). The UWB channel model is the result of signal reflection, diffraction, multipath, and attenuation due to distance and carrier frequency. The channel model is suitable for use in the design of UWB communications for in-chip 3-D integration.
