Abstract  Abstract

A spread code to be allocated to transmission data is changed at a previous transmitting time and a next transmission time. For example at transmission of the first packet (first transmission) symbols 1 to 4 are spread by spread code #0 while at transmission of the second packet (retransmission) symbols 1 to 4 are spread by spread code #1. As a result since despread signals of the respective symbols obtained by a plurality of reception times on a receiver side are synthesized it is possible to eliminate a reception symbol having an extremely small reception level so that reception quality can be improved.
