Claim 8:
9. The electronic device of claim 1, wherein:
the first multi-dimensional modulation symbol block and the second multi-dimensional modulation symbol block are a first two-dimensional modulation symbol block and a second two-dimensional modulation symbol block, respectively, and
the first transformation includes one of:
applying a one-dimensional Fourier transform to each row of the first two-dimensional modulation symbol block to obtain an intermediate two-dimensional modulation symbol block, and then applying a one-dimensional inverse Fourier transform to each column of the intermediate two-dimensional modulation symbol block to obtain the second two-dimensional modulation symbol block; or
applying a one-dimensional inverse Fourier transform to each column of the first two-dimensional modulation symbol block to obtain an intermediate two-dimensional modulation symbol block, and then applying a one-dimensional Fourier transform to each row of the intermediate two-dimensional modulation symbol block to obtain the second two-dimensional modulation symbol block.
