G In the GM receiver, there is a phase error (\theta (t)) when the tone signal generated by the local oscillator is matched by the carrier of the received signal, cos(2\pi f_(c)t). Assume that \theta (t) phase error is uniformly distributed along [-\delta , \delta ] and \delta ≪1. Additionally, there is a narrow band determined by the power spectral density (N_(0))/(2) in the range f_(c)-W<=|f|<=f_(c)+W, with the mean value of n(t) being zero. Assume that there is a band noise process and is expressed as: n(t)=n_(c)(t)cos(2\pi f_(c)t)-n_(s)(t)sin(2\pi f_(c) )
Let's assume that the information signal has W bandwidth and P power. In this case, the phase of the carrier (\theta (t))
- AGS is low pass filter and D.A. bastırıcı is DC Suppressor
and noise is defined as the expected value of the square of the difference between the receiver output when n(t)\theta (t)!=0 and the information signal component of the receiver output when \theta (t)=0.
