In a code division multiple access (CDMA) signal demodulator in a communication system (50), samples of a CDMA signal are stored in a sample buffer (52). A plurality of the samples that represent a plurality of chips of a symbol are then recalled from the sample buffer (52). Thereafter, the plurality of samples are demodulated in parallel (56) using a selected user code (68) to produce at least a portion of a user's symbol in the code division multiple access signal. Signals from multiple users (22, 24) having multiple fingers are demodulated by sharing the resources of a parallel demodulator (56). Signal searching may use the same parallel demodulator (56). Fingers for multiple users may be dynamically allocated and reallocated according to the needs of each user's signal and the total demodulation resources available.

[ What is claimed is:] [1.] A method of demodulating a code division multiple access (CDMA) signal for multiple users in a communication system:storing samples of said CDMA signal in a sample buffer, wherein said CDMA signal includes signals from multiple users, and wherein a number of samples stored represents complete corresponding symbols in a selected frame from each of the multiple users;recalling a first plurality of said samples from said sample buffer that represent a plurality of chips in a signal from a first one of said multiple users;demodulating said first plurality of said samples using a first user code to produce at least a portion of a first user's symbol in said code division multiple access signal;recalling a second plurality of said samples from said sample buffer that represent a plurality of chips in a signal from a second one of said multiple users; anddemodulating said second plurality of said samples using a second user code to produce at least a portion of a second user's symbol in said code division multiple access signal.
