Abstract:
A bit sequence generator for generating a bit sequence defined by a generating function and an initial state of the generating function comprising a plurality of state machines and a multiplexer. Each state machine of the plurality of state machines generates a time-interleaved bit sequence, wherein a state machine generates a bit of the time-interleaved bit sequence for a current time step based on at least one bit generated by the state machine for a preceding time step, the generating function of the bit sequence to be generated, and the initial state of the generating function and independent from a time-interleaved bit sequence generated by another state machine of the plurality of state machines. Further, a multiplexer selects successively one bit from each generated time-interleaved bit sequence in a repetitive manner to obtain the bit sequence defined by the generating function and the initial state of the generating function.
