1)   A communication system uses 16 QAM with a rolloff factor of 0.1. The available bandwidth is 6MHz. The signal power at the receiver is 1W and the noise power is 0.05.

a.   Find the maximum bit rate one can have if the BER is required to be less than 10-5.

b.   What would be the probability of error if the transmission rate was 10Mbps.
