In this paper, a modified energy detection scheme using the pseudo BER based SNR estimation is investigated. In the proposed scheme, the pseudo BER is used to estimate the signal-noise-ratio (SNR) of the primary signal for the modified energy detection scheme at the secondary users. We have shown that with the assistance of the pseudo BER based SNR estimation, this modified energy detector outperforms traditional energy detector under the noise uncertainty in the run-time. In addition, the simulation results show that the proposed scheme can achieve the required detection performance and reliably alleviate the SNR wall effect as well.
