Question

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.

What is the appropriate range of the symbol duration of OFDM signals?

Problem 3:

Answer 1

In order to answer the following electronics question, you have to provide a paper in which you have to provide answer to each part, by showing its whole computation part. Question 1: The accessible bandwidth in a cluster is 1.25MHz. Determine the number of channels per cell for the given 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. Question 2: The delay spread in the environment TD is 5 micro seconds. The maximum Doppler spread FD is 200Hz. Determine the suitable range of the symbol for the period of OFDM signals?
