In telecommunications, the delay spread is a measure of the multipath richness of a communications channel. In general, it can be interpreted as the difference between the time of arrival of the earliest significant multipath component (typically the line-of-sight component) and the time of arrival of the last multipath components. The delay spread is mostly used in the characterization of wireless channels, but it also applies to any other multipath channel (e.g. mul… WebFaculty of Information Engineering & Technology The Communications Department Course: Wireless Communications [NETW 701] Dr. Tallal Elshabrawy Tutorial (5) Problem (1): Calculate the RMS delay spread for an HF radio channel for which: 𝑷 (𝝉) = 𝟎. 𝟔𝜹 (𝝉) + 𝟎. 𝟑𝜹 (𝝉 − 𝟎. 𝟐) + 𝟎. 𝟏𝜹 (𝝉 − 𝟎 …
