ABSTRACT:
An object of the present invention is to provide a communications system etc., which can reduce the influence of interference from other systems which results from a difference in symbol length, in an area where a plurality of systems using different transmission methods are mixed. The present invention relates to a communications system in which a plurality of systems share the same frequency bandwidth so as to transmit information symbols. One of the plurality of systems1includes an identifying unit109configured to identify the symbol length of an information symbol transmitted in a different system2; and an adjusting unit102, 107configured to adjust the symbol length of an information symbol to be transmitted, in accordance with an identified symbol length.
