A binary FSK system transmits data at the rate of 2.5 megabits per second. During the course of transmission, white Gaussian noise of zero mean and power spectral density 10^(-20) watts per hertz is added to the signal. In the absence of noise, the amplitude of the received signal is 1 μV across 50-ohm impedance. Determine the average probability of error assuming coherent detection of the binary F5K signal.[Hint: Energy per bit is given by Eb = Ac² T/2R , where Ac is the signal amplitude, T is the bit duration and R is the impedance of the load.]

Answer:

See explaination

Explanation:

Power Spectral Density (PSD) is the measure of signal's power content versus frequency. A PSD is typically used to characterize broadband random signals. The amplitude of the PSD is normalized by the spectral resolution employed to digitize the signal.
