Abstract
A demodulator system for a receiver in a multiple user-code spread-spectrum system, such as in a CDMA base station, utilizes a Quasi-Newtonian optimization routine to identify received codes and recover user data based on detected correlations between the received spread-spectrum signal and a set of the possible codes available to users of the system. The preferred optimization routine is a Davis-Fletcher-Powell (DFP) routine.
