HIGH-SPEED RADIO TRANSMISSION METHOD BASED ON CHIRP SPREAD SPECTRUM MODULATION, AND HIGH-SPEED RADIO TRANSMISSION SYSTEM

摘要

The present invention relates to a high-speed radio transmission system based on a chirp spread spectrum (CSS) modulation. The present invention includes a first mapping unit which uses a 16-ary binary-to-bipolar symbol mapping table to generate 16 code-words and have a code-rate which is one to use user data of eight bits per a full chirp signal. Thereby, the present invention performs the high-speed data transmission of 1.33 Mbps and maintains physical properties with the strength of a distance ranging by using the 16-ary binary-to-bipolar symbol mapping table whose code-rate is one.
