Underwater acoustic (UWA) sensor networks demand high-rate communications with high reliability between sensor nodes for massive data transmission. Filtered multitone (FMT) is an attractive multicarrier technique used in high-rate UWA communications. and can obviously shorten the span of intersymbol interference (ISI) with high spectral efficiency and low frequency offset sensitivity ... https://parisnaturalfoodes.shop/product-category/cinnamon-quills/
