Question

A continuously operating coherent Binary Phase Shift Keying (BPSK) system is made by an engineer. He claims that it is having an average error probability of 10-5. The system produced 1000 errors in a day when tested with a data rate of 500 bits/s and the single-sided noise power spectral density is No=10-10 W/Hz. He also claim that the system is capable of maintaining the error rate even if the received power is as low as 10-6 W. Do you agree with his claims? Give justifications to your answer.
