Question

b) A digital cellular telephone system is required to work at a bandwidth efficiency of 5 bits/second/Hz in order to accommodate sufficient users to make it profitable. What is the minimum signal to noise ratio per bit (E,/No) that must be (4) planned for in order to ensure that users on the edge of the coverage area receive error-free communication? If we wish to maintain the bandwidth efficiency and double the data rate in the system, what would be the possible solution we could provide? If the bandwidth is fixed, and required data rate is doubled, what is impact on the system design? Provide your reasoning with mathematical derivation.
