Title: Encoding modulation/demodulation method for realizing variable transmission speed
Inventor: OKAMOTO EIJI
IPC: H03M13/25
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To provide an encoding modulation/demodulation method for realizing variable transmission speed by which reduction of a bit error rate is enabled without lowering power efficiency by block encoding which does not use a complicated means such as demodulator switching or an index signal in the collective transmission of frames different in transmission speed. SOLUTION: A block encoding modulation system where signal points different in the number of bits are arranged on the same signal space diagram face is constituted on the same channel and the signal points are properly selected. Thus, variable speed transmission is realized. In such a case, although an Euclidean distance between the signal points is reduced by the increase of the signal points resulting in possible deterioration in transmission characteristic, it is avoided by using the block encoding modulation system. Then, the error of the number of the transmission bits of a symbol is prevented by a method for encoding transmission bit information and incorporating it in a transmission code and a method for using set division.
