Identification of protein coding regions (exons) in eukaryotic genomic sequences is an active area of research at present. Mapping of symbolic genomic sequences to numeric sequences is the first step required for processing them using digital signal processing (DSP) tools. For DFT-based methods paired numeric and frequency of nucleotide are reported as the best mapping schemes. In this work performance...
A simple algorithm to improvise the identification of protein coding regions in DNA sequences by period-3 property is presented. Background noise present in the period-3 DNA spectrum has been captured using DFT and notch filter. Elimination of this noise from the DNA spectrum improvised the detection of protein coding regions. Algorithm is data independent as it does not requires the empirical determination...
We show that one can do away with the cyclic prefix (CP) for SC-FDE and OFDM at the cost of a moderate increase in complexity of a DFT-based receiver. Such an approach effectively deals with the decrease in the number of channel uses due to the introduction of the CP. It is shown that the SINR for SC-FDE remains the same asymptotically with the proposed receiver without CP as that of the conventional...
