<p><P>PROBLEM TO BE SOLVED: To provide a signal sequence generation circuit which can handle a lot of information without complicating a system configuration or the like, and also can generate a signal sequence excellent in noise resistance. <P>SOLUTION: The signal sequence generation circuit comprises: a multiple M-sequence generating means for generating a plurality of M sequences to be a preferred pair with each other when taken out and watched two by two; a variable delay applying means for applying delay to the plurality of M sequences generated, respectively; and an addition means which applies exclusive OR operation to the plurality of M sequences delayed and outputs signal sequences after the operation. It is preferable herein that the number of M sequences generated by the multiple M-sequence generating means is equal to the maximum number of sequences to be a preferred pair, in a degree thereof, with each other when taken out and watched two by two. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
