Abstract
The Digital Terrestrial Multimedia Broadcast (DTMB) system utilizes three modes of Pseudo-noise (PN) sequences as Frame Header (FH) that can be exploited for spectrum sensing on TV White Space (TVWS). As a consequence, multi-mode signal detection is required at the receiver. In this paper, Neyman-Person (NP) lemma based, Multi-mode Local Sequence (MLS) detectors are proposed for multi-mode signal detection. The theoretical and quantitative performance analysis of MLS detectors are mainly concentrated and fully studied by utilizing the addition and auto-correlation properties of PN sequence. In addition, the single-mode detector for the DTMB system is presented as the optimal detector and taken as a benchmark for MLS detectors. Both theoretical analyses and simulation results show that MLS detectors are capable of multi-mode signal detection and satisfy the predefined sensing requirements.
