Homework Statement
A sine wave is to be used for two different signaling schemes: (a) PSK; (b) QPSK. The
duration of a signal element is 10^-5 s. If the received signal is of the following form
s(t) = 0.005 sin(2pi (10^6)t + theta) volts and if the measured noise power at the receiver is 2.5 X 10^-8 ,watts, determine the Eb/No(in dB) for each case.
Homework Equations
s(t) = 0.005 sin(2pi (10^6)t + theta) volts
Eb/No = ?
signal element = 10^-5s
The Attempt at a Solution
I'm not sure where to start this problem, I assume the 10^-5s should be put into the main equation but I'm not sure what theta equals and what variable I will be solving for. Any help would be appeciated.
