Sensitivity of compressive receivers

Two methods to calculate compressive receiver sensitivity are shown. The broadband method uses the whole bandwidth of the compression line and applies a weighting calculation for the noise and the signal attenuations. In the narrowband method, the bandwidth of the compression line, divided by the effective compression factor is used to determine the noise level before the detector, to which the broadband noise from the detector is added, giving the total noise level in the detector. The two approaches can be combined, and present the same analytical expression for receiver sensitivity.
