The value of the input SNR at threshold is often defined as the value of P T
Question:
The value of the input SNR at threshold is often defined as the value of PT / N0W at which the denominator of (8.172) is equal to 2. Note that this value yields a post detection SNR, (SNR)D, that is 3 dB below the value of (SNR)D predicted by the above threshold (linear) analysis. Using this definition of threshold, plot the threshold value of PT / N0W (in decibels) as a function of β. What do you conclude?
