A radio receiver has antenna noise temperature of 3000 K and equivalent noise temperature of 7000 K for its feeder and amplifier cascade.
It requires Eb/No = 15 dB to provide Probability of error of 10^-15 (using BPSK). Its operating bit rate is 10 Mbps.
Find :
a) Its system noise power spectral density
b) The Required average energy per bit
c) The Required signal strength
