Abstract

Abstract:

A novel Cognitive UWB spectrum sensing algorithm is proposed and evaluated, which enables the detection of the low average SNR and low duty ratio signal with low complexity and small detection delay. An uniform probability density function of the low duty ratio received signal is constructed based on the characteristic of the UWB pulse signal. CUSUM test is introduced to implement the detection. Theoretical analysis indicates that the proposed algorithm is suitable for low duty ratio signal detection. Compared with the energy detection algorithm, the proposed algorithm conquers the SNR wall phenomenon, with superior detection delay performance. Furthermore, the theoretical analysis results are proved by simulations.

Key words: cognitive UWB (CUWB), spectrum sensing, cumulate sum (CUSUM), detection delay
