<P>PROBLEM TO BE SOLVED: To reduce multipath interference (MPI) equally to an OFDM (Orthogonal Frequency Division Multiplexing) system without using a multipath canceler. <P>SOLUTION: A wavenumber division multiplex transmitting method for transmitting data with a wave number spectrum specific to a symbol and a mobile station includes: encoding transmission data; modulating the encoded data; compressing a time domain of each of symbols in a data-modulated transmission symbol sequence; repeating the symbol predetermined times; permuting the symbols in the resultant repeating symbol sequence to be an array of the transmission symbol sequence; generating a code having the predetermined number of waves constituting a Walsh code as a spreading code of the symbol for each of symbols in the repeating symbol sequence; and multiplying each of symbols in the repeating symbol sequence by the spreading code and spreading each of the symbols. <P>COPYRIGHT: (C)2011,JPO&INPIT |
