Wavelets are bandlimited, continuous-time waveforms that are
orthogonal to their dyadic dilations and translations and have
localized support in temporal and spectral domains. These and other
appealing properties allow us to explain most of the functions of a
pulse code modulation (PCM) system, namely, sampling, compression and
line coding and Nyquist's zero intersymbol interference (ISI)
condition for waveform design. In fact, the bandlimited raised-cosine
family of waveforms is a special case of the Meyer family of wavelets.
Transmitter and receiver design, bit error rates, bandwidth
efficiencies and ISI implications arising in communication system
designs employing both continuous- and discrete-time wavelets are
considered in this tutorial. We shall also consider wavelet-based
spread spectrum signal sets whose traffic capacity per unit
bandwidth can be made to exceed what is possible in other CDMA
