Chirp Spread Spectrum Transceiver Design and Implementation for Real Time Locating System
International Journal of Distributed Sensor Networks, 2015 A chirp spread spectrum (CSS) transceiver architecture for IEEE 802.15.4a is proposed and implemented. In the transmitter, the size of the read-only memory that stores CSS signal samples for the chirp modulator is reduced by removing duplicate samples ...

Evaluation of bistable systems versus matched filters in detecting bipolar pulse signals
, 2004 This paper presents a thorough evaluation of a bistable system versus a matched filter in detecting bipolar pulse signals. The detectability of the bistable system can be optimized by adding noise, i.e. the stochastic resonance (SR) phenomenon.
