Inventive methods and apparatus for use in simultaneously generating two or more pseudorandom noise (PN) sequences for spread spectrum communications are described. A data sequence generator includes a data access module and a multiplexing device. The multiplexing device has inputs to receive first counter values associated with a first demodulator and second counter values associated with a second demodulator. The multiplexing device has an output to provide, in an interleaved fashion, the first counter values and the second counter values to an input to the data access module. An output from the data access module provides, in an interleaved fashion, PN sequence data responsive to the first counter values and PN sequence data responsive to the second counter values for the first and the second demodulators, respectively. Preferably the data access module is a read-only memory (ROM) having the PN sequence stored therein.
