Abstract
A wideband code division multiple access, spread-spectrum communications system, having an equalization channel. The transmitter transmits data over a spread-spectrum channel, along with a spread-spectrum channel having little or no information, i.e., an equalization channel. The receiver uses in-phase early, punctual and late signals, and quadrature-phase early, punctual and late signals, for equalizing of the data spread-spectrum channel, and for generating an output in-phase data signal and an output quadrature-phase data signal.
