This project analyzes the performance of cooperative spectrum sensing with enhanced energy detectors. Cognitive radios (CRs) employ improved energy detection algorithms to determine primary user (PU) presence. The implementation evaluates total probability of error across varying numbers of CRs under different SNR conditions, with a relative threshold set at 10 dB. Key aspects include collaborative decision fusion and energy detection optimization.
