Abstract

The impulse response of the radio channel can typically be decomposed into a specular part and diffuse part. Neglecting the diffuse multipath components (DMC) in the channel model may result in underestimating the received power and the channel capacity. Therefore, it is important to analyze the power contribution of the DMC. This work presents an analysis of the fractional DMC power. A wideband channel measurement campaign was conducted at 5.2 GHz. The Kalman enhanced super resolution tracking (KEST) algorithm is used to estimate the parameters of the specular multipath components (SMC). The results show that the value of the fractional DMC power depends on the shadowing condition. While the DMC contributes as low as 5% in line-of-sight (LoS) situation prior to the collision, it varies between 15% and 40% in obstructed-LoS (OLoS), and it can reach up to 90% in non-LoS (NLoS) situation.
