Abstract

Provided is a transmission method that converts an encoded block of data into first complex symbols each including a real component and an imaginary component, one or which is designated as a first component and the other as a second component; writes the first components and the second components of the first complex symbols respectively column by column into a first interleaver matrix and a second interleaver matrix having N R rows; applies a cyclic shift to each column of the second interleaver matrix in accordance with a predetermined shift pattern; and reads the first components from the first interleaver matrix and the second components from the cyclically shifted second interleaver matrix row by row. N R is a multiple of N RF greater than N RF (N RF being an integer greater than one), and the shift pattern for the cyclic shift includes only integers that are not a multiple of N RF .

First claim

The invention claimed is:

1. A transmission method for transmitting digital data over N RF frequency channels (N RF being an integer greater than one), the transmission method comprising the steps of:
encoding a block of data of a predetermined length with an error correction code;
mapping the encoded block of data to a sequence of real-valued symbols a predetermined number of bits at a time;
generating first complex symbols each including a real component and an imaginary c…
