Abstract
A system and method for assigning channelization (spreading) codes in CDMA communication networks using spread spectrum modulation techniques such that a minimum number of spreading codes are assigned by using an optimal codeword. A system codeword of a predetermined weight representing spreading codes for different spreading factors in the spread spectrum communication system is used, in conjunction with a user defined weight, to determine the optimal codeword such that a minimum number of spreading codes are assigned therewith.
