m Sequence and Its Application in Communication
Wang Yuan-yi · Modern Electronics Technique · 2009
The primitive polynomial,the generation way of m sequence and its application in communication are introduced.The self-correlative property of m sequence is good,it has pseudo random property and it is easy to be generated and copide.It mainly be applied to spread spectrum and encryption.The spread spectrum widening through the modulation that the waitting transmission message by the high speed pseudo-random sequence(spread spectrum sequence) to achieve.At the receiver,using the same spread spectrum codes to finish the despreader.The encryption maks use of m sequence to carry the primary information which has the pseudonoise characteristic,achieveing the goal that hides the information in the signaling process.
