Patent ID: 7808883

Claim:
A method, comprising: assigning at least one of a set of symbols to a first carrier of a set of N carriers, and assigning an antipodal representative of said at least one of said set of symbols to a second carrier of said set of N carriers for multicarrier modulation configured to be used in a transmitter and transmitting by the transmitter the set of symbols on the assigned carriers; wherein a complex conjugate representative of said at least one of said set of symbols, which is associated with said first carrier, is assigned to a third carrier, and a complex conjugate representative of said antipodal representative, which is associated with said second carrier, is assigned to a fourth carrier, and wherein said set of N carriers is associated with a set of N carrier frequencies, wherein each carrier frequency is represented by f i with index i ε {0,1, . . . , N−1}, and wherein said carrier frequencies f i are arranged via index i by an increasing order of said carrier frequencies, and wherein a carrier frequency of said first carrier is represented by f k with k ε {0,1, . . . , N−1}, and wherein a carrier frequency of said second carrier is represented by f l , wherein l ε {0, . . . , N−1} and l≠k holds; and wherein a carrier frequency f N-l-k is associated with said third carrier and wherein a carrier frequency f N-1-l is associated with said fourth carrier and wherein carrier frequencies of said first carrier and said second carrier are assigned to adjacent carrier frequencies.
