Q2: [7 points]
For the multipath profile given in the figure below,
find:
+2+2+1 points] [A1, B1, C1, C2]
a) the mean excess delay,
b) rms delay spread,
c) the 50% coherence bandwidth of the channel.
d) the maximum bit rate that can be sent through the channel
(If QPSK modulation is used) without needing an
equalizer if $\frac{\sigma_\tau}{T} \leq 0.1$
