Abstract

An alternative code division multiple access (CDMA) scheme to spread spectrum (SS), called spread-time (ST), is proposed for bandlimited multiple access channels. ST-CDMA can be considered the time-frequency dual of SS-CDMA. Implementations are described in which surface acoustic wave (SAW) devices are used to perform the matched filtering or Fourier transformation. A first-order comparison of signal-to-interference ratio and spectral efficiency is given for ST- and conventional asynchronous SS-CDMA, assuming an ideal bandlimited channel.
