Two LTE operators (Vodo and Red) are working on the following bands

Vodo: 910MHz-915MHz and 950MHz -955MHz

Red: 915MHz-920MHz and 955MHz-960MHz

Noise variance is normalized to 1; and transmit power of P=1W can be also assumed.

For Vodo operator, the average SNR in its bands is 3.2, and for Red is 3.1

1.1 Fully design Vodo OFDM system with all the practical considerations to obtain the data rate of the OFDM system. Clearly state the design parameters and the values you assume for them. Your assumptions have to be logical and realistic.

1.2 Based on the design in 1.1, what is the average total data rate for Vodo with your design?

In order to increase the system efficiency, Red proposed to Vodo to make an exchange of bands, so that each operator has its two bands to be adjacent.

1.3 Explain why this proposal can increase the system efficiency.

1.4 How would the design change with respect to 1.1 ?

1.5 What is the new average data rate that the Vodo customer will achieve in this modified system?
