DIGITAL WIRELESS TRANSMISSION METHOD AND RECEIVER EMPLOYING THE SAME, TRANSMISSION APPARATUS, AND MOBILE WIRELESS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a digital wireless transmission system adopting a multi-valued modulation system such as an amplitude phase modulation and a phase shift keying modulation system that has excellent tracking performance even against disturbance such as fading, and has a comparatively high transmission efficiency.

SOLUTION: A transmitter side modulates a signal on the basis of a symbol sequence wherein information is assigned by a modulation method A whose number of modulation values is m and a modulation method B whose number of modulation values is n (2≤nCOPYRIGHT: (C)2004,JPO
