    In signal detection for cognitive radio, it is desirable to calculate a threshold within a short observation period since noise power changes in accordance with the amplification factor and the temperature of a low noise amplifier in a receiver. This paper proposes a threshold calculation scheme with a filter bank. The proposed scheme uses a more number of noise samples output from the filter bank to calculate the threshold. Thus, the proposed scheme can improve the accuracy of the calculated thresholds and it leads to increase the probability of detection. Numerical results obtained through computer simulation show that the proposed scheme reduces the required sample per energy by 0.5dB at a detection probability of 0.99.
