SNR enhancement method for energy detection
ICTC（2012）
摘要
The proposed method is intended to improve the performance of the classical energy detector. The method preserves the characteristic advantages of the energy detector while simultaneously achieves SNR gain and variance reduction. We utilize the Welch method as the basic platform of analysis, derive performance function, and perform computer simulations to confirm the performance function. We also show the performance improvement of the proposed method employing SNR and ROC curves.
