Bit Error Rate analysis using Converged Welch's Method for Energy Detection Spectrum Sensing in Cognitive Radio.

In this Letter, a novel approach is used for improving the Bit Error Rate (BER) for non-stationary environment based spectrum sensing. Here, we have considered Converged Welch's Power Spectral Density (PSD) for analyzing of power. The signal of interest is thus further studied in terms of BER keeping the antenna and channel parameters constant. The proposed method yields an improvement of 34.6% as compared with the conventional method. [ABSTRACT FROM AUTHOR]
