Energy Detection Characteristics of the Quasi-Deterministic Signal with the Nakagami Amplitude

摘要

We studied the possibility of applying power method for the radio signal detection against Gaussian white noise. It is presupposed that the signal amplitude is random and distributed by the Nakagami law. For this case, we found the distribution of the decision statistics of the energy detector. We obtained the expressions for the probability of correct detection under the discrete processing of the observable data realization within the limited time interval. We also analyzed the influence of the average power signal-to-noise ratio value and the time-bandwidth product upon the detection characteristics.
