Abstract

3GPP Typical Urban Area channel model is used to measure the performance of different systems. This paper showed that the channel imposes a slow fading effect at fd = 5 Hz and fast fading effect at fd = 100 Hz. This effect is caused by the user mobility. A further analysis shows that Typical Urban Areas tend to be frequency selective for wide band signals with a coherence bandwidth equals to half of the transmitted bandwidth. The mobility of users decides how fast the fading is affecting the transmitted signals. For low mobility condition (fd = 5 Hz), the channel shows a significant change every 25 (ms) which is quite slow according to the delay requirements of wide band communication. However, as the mobility increases (fd = 100 Hz) the channel tends to vary significantly in the order of few milliseconds.
