Abstract:
A data sequence generator operative to provide pseudorandom noise (PN) sequences for spread spectrum communications, comprising:a multiplexer, including: inputs to receive first counter values associated with a first demodulator and second counter values associated with a second demodulator; and an output to provide, in a multiplexed fashion, the first counter values and the second counter values; a converter, for receiving the first counter values and for generating the second counter values responsive to the first counter values; and a data access module having at least one pseudorandom noise (PN) sequence comprising I and Q PN sequences, used for in-phase and quadrature spreading respectively, encoded therein, having an input coupled to the output of the multiplexer, and having an output to provide, in a time-multiplexed fashion, PN sequence data responsive to the first counter values and PN sequence data responsive to the second counter values.
