Abstract: An embodiment of the invention described in the specification and drawings is an apparatus and method of generating a phase-shifted maximum length pseudo-random noise (PN) sequence without resorting to complicated counters and clocking schemes. The apparatus includes a linear feedback shift register (LFSR) that has N stages and the ability to generate a first PN sequence at an output of its last stage. The LFSR is coupled to a first mask circuit and a second mask circuit for generating a second PN sequence and a third PN sequence. The apparatus further includes logic for selectively outputting bits from the second and third PN sequences to form a fourth PN sequence, which has a phase shift relative to the first PN sequence.

Abstract: A method and apparatus for processing a secondary synchronization channel in a spread spectrum system is disclosed herein. The method includes several steps, the first of which is to receive a first input data at a correlator. Next, a first code sequence of a code group is received at the correlator. The first correlator then correlates the first input data with the first code sequence. Afterward, a second code sequence is received at the correlator. This time, the first input data is correlated with the second code sequence. Correlation of both the first code sequence and the second code sequence occurs prior to receiving a second input data. Lastly, correlation results from the first correlator are compared with a threshold value using a threshold detector.
