1. You are to design a 9-volt battery operated baseband PAM communication system that must last
great than 10 years without replacing the batteries. The application requires a BER of <10^-4 and a data
rate of 200bps. The channel can be modeled as AWGN with a noise power spectral density of 10^-9
W/Hz and a channel loss of 10 dB.
(a) Estimate the required capacity of the batteries. (The battery life (hours) is equal to the
battery volts times of the battery capacity (Amps* hours) divided by the total load (Watts)) and
(b) Can you easily find this battery? If not, what would you suggest be done?
