1. A wireless communications method, comprising: employing a processor executing computer executable instructions stored on a computer readable storage medium to implement the following acts: generating cyclic shifts for a sequence generator by masking output values from a shift register with one or more masking vectors; generating one or more m-parameters for the sequence generator in accordance with the one or more masking vectors, wherein different mask values are applied to at least two sets of the one or more m-parameters; and forwarding the sequence generator to a desired future sequence state based in part on the output values, the generated one or more m-parameters, and the one or more masking vectors, wherein forwarding the sequence generator to a desired future sequence state comprises: generating a sequence of bits occurring just before the desired future sequence state, using the one or more m-parameters; and employing the generated sequence of bits to initialize the shift register.
