METHODS FOR GENERATING MULTI-LEVEL PSEUDO-RANDOM SEQUENCES

摘要

A method for generating multi-level (or multi-bit) pseudo-random sequences is disclosed which relates to communication systems, and more particularly to generating multi-level pseudo random bit sequence. Further, these systems do not cover all the possible transitions for the outputs of the system. The proposed system employs mechanisms in order to generate PRBS signals for producing multi levels signals to the electronic components. The mechanism employs alternate bit tapping techniques. In the alternate bit tapping technique, bits are tapped alternatively to determine the current state and the next state of the system. In addition, the mechanism also covers all the possible states of the output vector with transitions between the output states. This ensures that high data rates are obtained for a given bandwidth of operation.
