<P>PROBLEM TO BE SOLVED: To provide a technique for using a plurality of modulation methods for retransmission of augmentative redundancy, etc. of a single packet. <P>SOLUTION: Each data packet is processed and is transmitted with a block of T at the maximum, where T>1. In order to achieve proper performance, a plurality of modulation methods are used for the block of T. A transmitter encodes the data packet to generate a code bit. Next, the transmitter generate a code bit block using the code bit generated for the packet, and determines a modulation method to be used for the block (based on a selected mode/rate). Then, the transmitter maps the code bit for the block based on the modulation method to obtain a data symbol, and processes and transmits a data symbol block to a receiver. The transmitter generates and transmits other blocks by the same method until a data packet is decoded correctly or all T blocks are transmitted. <P>COPYRIGHT: (C)2010,JPO&INPIT |
