This paper proposes a novel method for acoustically and wirelessly transmitting data underwater with a high transmission rate. The method uses the most promising physical layer and multiple access technique (i.e., the code division multiple channel access technique) to divide the channel into subchannels. Data is transmitted through these subchannels. The(More)
In many communication systems, the Gaussian mixture model (GMM) is widely used to characterize non-Gaussian man-made and natural interference. The envelope distribution of such noise model is often expressed as a weighted sum of Rayleigh if in-phase and quadrature components of the noise are dependent. Instead, in this paper, a simple and exact closed form(More)
The dissociation of protonated peptides containing adjacent arginines has been studied by electrospray ionization-tandem mass spectrometry (ESI MS/MS) and theoretical calculations. The experimental results show that singly protonated peptides cleave at the Arg-Arg amide bond and generate the y(1) ion when adjacent arginines are the C-terminal residues. The(More)
