Abstract :
In this paper, a novel space-time-Doppler estimation and reception algorithm is proposed for single-hop sensor network operating in a harsh environmental condition. The algorithm can perform irregardless of whether the central receiver and/or sensor nodes are in motion or in static position. It requires no knowledge of the channel and is resistant against MAI, ISI and other near-far interferences as a result of strong near-distant sensor nodes or weakened transmitted signal power. The improvement does not impose additional processing burden on the sensor nodes, but instead on the central receiver itself.
