Claim:
1. A method of data allocation, suitable for a wireless transmitting apparatus, wherein the wireless transmitting apparatus transmits through a plurality of sub-carriers based on an orthogonal frequency division multiplexing (OFDM) technology, the method comprising: obtaining a data stream; allocating the data stream to a first sub-carrier set, wherein all the sub-carriers are divided into the first sub-carrier set and a second sub-carrier set, and the first sub-carrier set and the second sub-carrier set respectively have the sub-carriers with opposite frequencies to each other, wherein the number of the sub-carriers is N, the first sub-carrier set comprises a first sub-carrier to an (N/2)−1 emptying the second sub-carrier set or allocating the second sub-carrier set based on the data stream allocated to the first sub-carrier set, wherein the method of allocating the second sub-carrier set comprises performing a complex conjugate computation to the data stream allocated to the first sub-carrier set, and allocating the data stream after the complex conjugate computation to the second sub-carrier set, wherein allocating data stream after the complex conjugate computation in an mth sub-carrier in the first sub-carrier set to an −mth sub-carrier in the second sub-carrier set, wherein m is from 1 to (N/2)−1.
