Abstract:
A method of establishing a communication channel between a base station and a mobile station, comprising:(a) generating control signals and data signals within the communication channel, said control signals having a first sequence of L-bits and a second sequence of L-bits; (b) autocorrelating the first and second sequences to generate first and second autocorrelated values; (c) cross-correlating the first and second sequences to generate first and second cross-correlated values; and (d) combining the first and second autocorrelated values and the first and second cross-correlated values, wherein the communication channel comprises a plurality of frames, each frame having L number of slots and each slot has N number of pilot bits such that there are N number of sequences of L-bits in a frame, said first and second sequences being sequences of the N number of sequences.
