Abstract
A modulation method for a first data string having a plurality of symbols is disclosed. The method includes: appending a data string to the first data string to form a second data string; and converting the second data string to a code word sequence by converting each of the symbols in the first data string to a code word according to predetermined modulation rules and a symbol set selected from the second data string. Each code word has a first fixed number of bits, each symbol has a second fixed number of bits, and each symbol set has a fixed number of symbols.
