    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.
