mSequences
Maximum Length PN sequences are binary sequence generators that are capable of outputting all possible combinations of binary sequences in 2^m-1 cyclic shifts, where m is the size of the LFSR (Linear Feedback Shift Registers ) used in generating such sequences. Terms like Psuedorandom binary sequences (PRBS) or psuedonoise sequences are also used to refer m-sequences.
