Abstract:
1. An interleaving method implemented by a transmitter that transmits a plurality of D-dimensional rotated constellations (D being a power of two) over N RF frequency channels (N RF being an integer greater than one), each D-dimensional constellation being composed of D/2 real components and D/2 imaginary components, the interleaving method comprising the steps of: writing a series of real components, column by column, into a first interleaver matrix having N applying a cyclic shift to either the columns of the first interleaver matrix or the columns of the second interleaver matrix in accordance with a predetermined shift pattern; and reading the real components from the first interleaver matrix row by row and the imaginary components from the second interleaver matrix row by row to generate a plurality of complex symbols, after the applying of the cycle shift, wherein N the shift pattern for the cyclic shift includes only integers that are not a multiple of N each of the N
