摘要： An OFDM transmitter and receiver. The OFDM transmitter comprises a first symbol generator for generating first and second control symbols each 5 comprising a leading guard interval, a useful interval and a trailing guard interval. The leading and trailing guard guard intervals of the first control symbol have first leading signals in which, respectively, a leading portion of the useful interval and a trailing portion of the useful interval have undergone a non-zero first frequency shift. The leading and trailing guard guard intervals of the second 10 control symbol have second leading signals in which, respectively, a leading portion of the useful interval and a trailing portion of the useful interval have undergone a non-zero second frequency shift. The first and second frequency shifts have different values to each other. The leading guard intervals differ in length, the trailing guard intervals differ in length, and the total length of the 15 leading guard interval and the trailing guard interval of the first and second control symbols are equal to total length. The OFDM transmitter also comprises a second symbol generator for generating a plurality of symbols different from the first and second control symbols, and a symbol inserter for inserting the first and second control symbols into the plurality of symbols. 7815459_1 (GHMatters) P90742.AU.2 AJM ca C")o =3= CC,, + co - Z---- - 0 ca co 4- coo co C 4-0) _0 L
