[Industry research] paper01 DL : 0: A FFT-based partial matched filter (PMF) acquisition threshold setting method for fast GPS acquisition is presented. Normal distribution and numerical fitting technique instead of real decision variable (DV) distribution are used in derivation to approximate the threshold expression, and the modification method for the threshold expression is also presented. The threshold expression is based on the individual FFT Doppler bin false alarm probability rather than the convention whole detector false alarm probability. The proposed threshold expression can be adjusted according to the false alarm probability, the noncoherent accumulation (NCA) length and the estimated noise variance. Furthermore we discuss the implementation of zero-padding FFT with its advantage and limitation. The performance is superior compared to the reference method in terms of signal-to-noise ratio (SNR) when detection and false alarm probabilities are used as measurement criteria.

[Program doc] pro-report DL : 0: SIGNAL DETECTION FOR SPECTRUM SENSING Spectrum sensing is a critical functionality in cognitive radio communications as it must be performed before allowing unlicensed users to access a vacant licensed band. Energy detector is also known as radiometer and it is most common method of spectrum sensing because of its low computational and implementation complexities. The coherent detector, also referred to as a matched filter, can improve detection performance if the primary transmitted signal, s, is deterministic and known a priori.
