m Sequence (MLS : Maximum Length Sequence)
mSequence is a kind of (special kind of) LFSR sequence. So in order for you to understand msequence, first you need to understand the concept of LFSR sequence. What is so special about msequence comparing to typical LFSR ? If you generate a sequence with LFSR, the output eventually repeats itself. But in most of the application, the purpose is to generate the longest possible nonrepeating sequence with a given number of shift registers (Taps). mSquence is a special type of LFSR which gives the longest nonrepeating sequence for each give number of taps. The wellknown msequence for various taps is shown in the following table.
