Wavelets for waveform coding of digital symbols
Prashant P. Gandhi, Sathyanarayan S. Rao, Ravikanth Pappu · IEEE Transactions on Signal Processing · 1997
A wavelet-based coder-decoder (codec) structure is defined for baseband waveform coding. Numerical results for bandwidth efficiency are given, and a comparison between several different wavelets is presented. Moreover, it is shown that wavelets obey the Nyquist pulse shaping condition and provide a unified framework for analog pulse shaping concepts of communications.
