The signal waveform design of wideband high frequency sonar is proposed. Using the ridge slope invariability property of wideband HFM signal, moving target parameter estimation is discussed. Real time results are presented and show the prospect of wideband HFM signals in underwater signal processing applications.
A compound method is presented for protein secondary structure prediction. The residue sequence was first substituted with corresponding hydrophobic values. Then the sequential hydrophobic values was processed by using discrete wavelet transform (DWT) for denoising and by using continuous wavelet transform (CWT) for roughly analyzing protein secondary structure. Finally, improved Chou-Fasman method...
