Patent ID: 7599425

Claim:
A CDMA receiving system comprising: a receiver that is configured to receive a composite signal that includes a plurality of information, signals; a first decoder, operably coupled to the receiver, that is configured to decode a first information signal of the plurality of information signals, wherein the decoder decodes the information signal by separately decoding segments of the information signal using segments of a first CDMA code that are shorter in length than the first CDMA code, to produce an intermediate value corresponding to the information signal associated with each segment; a second decoder, operable coupled to the receiver, that is configured to decode a second information signal of the plurality of information signals based on a second CDMA code; and a decorrelator configured to provide an output value based on the intermediate values, an output of the second decoder, and a correlation among a segment of the first CDMA code and the second CDMA code.
