- W4387490019 abstract "Discrete wavelet transforms (DWT) provide a promising approach to enhance the spectral efficiency of a communication system. With the use of this technique, more bits can be transmitted in fewer spectrums, thus improving the spectral efficiency of a communication system. This is achieved by designing wavelet transforms with a desired time-frequency localization, so that the signal can be spectrally spread across the frequency bands. Moreover, time-frequency spectrograms of data can be improved to better take advantage of the signal's spread across frequency bands, thereby assisting in accommodating increased signal traffic. In addition, the use of wavelet transforms makes possible reduced duration of frame headers, a factor which translates to improved spectral efficiency. This is because wavelet transforms are used to map frames which are smaller compared to those mapped with conventional blocks. In addition, the coding of wavelet transforms is simplified compared to the traditional block transform coding, allowing for higher spectral efficiencies. A significant advantage of DWT is that it provides flexibility in accommodating different types of signals in various frequency bands. This is because wavelet transforms can be adapted to the signal structure of the received information without losing its spectral efficiency. Finally, DWT can be used to effectively detect and eliminate noise, thereby mitigating the distortion of transmitted signals and further improving spectral efficiency." @default.
