A multipath fading channel has a multipath spread of Tm = 2 seconds and a Doppler spread Bd = 0.04 Hz. The total channel bandwidth available for signal transmission is W = 5 Hz. To reduce the effects of intersymbol interference, the signal designer selects a pulse duration of T = 20 seconds. (a) Determine the coherence bandwidth and the coherence time of the channel. (b) Is the channel frequency-selective? Explain. (c) Is the channel fading slowly or rapidly? Explain.

For a two-ray channel model, derive a formula for the multipath delay spread Tm. Simplify the formula when the transmitter-receiver separation is relatively large. a. b. Hint: Do some research and find out what Taylor series expansion is. Use it along with the given assumption to obtain an approximation. c. Calculate Tm for ht = 5 m, hr = 2 m, and d = 100 m.
