Problem 1
The available bandwidth in a cluster is 1.25MHz. Find the number of channels per cell
for the following systems:
a.) AMPS: 30kHz/channel 7cells/cluster;
b.) NMTa: 25kHz/channel 7cells/cluster;
c.)NMTb: 12.5kHz/channel 13cells/cluster;
d.) GSM:25kHz/channel 4cells/cluster;
e.)CDMA: 1.25kHz/channel 20channel/sector 1 cells/cluster 3 sectors/cell.
Problem 2
The delay spread in an environment TD is 5 micro seconds.
The maximum Doppler spread FD is 200Hz.
