Problem 3 Continued: b) (20pts) An update to the application requires a higher data rate. The channel bandwidth remains the same as part (a). The new data rate is 64 Kbps. The system is battery operated with a 9V battery that has a AmpHr rating of 600 mAmpHrs. Estimate how many days the battery will last. 3) (30pts) An application requires a bit rate of 18.2 Kbps and an error rate of less than 104. The channel has a noise power spectral density of 10-8 W/Hz. The channel attenuates the power in the signal by 5 dB. The system uses binary PAM baseband digital communication system with the minimum required bandwidth and a roll-off factor of 0.319. a) (10 pts) What is the estimated minimum required signal power (Pt) at the transmitter?
