Title:
DATA BLOCK SPREAD TYPE SPECTRUM SPREAD COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2006/043717
Kind Code:
A1
Abstract:
A spectrum spread communication method includes a step of generating a data block formed by a plurality of M bits of transmission data in the CDMA communication method, a step of modulating an orthogonal sinusoidal wave by the repeated series of the data block to generate a spread symbol, a step of transmitting the symbol, a step of performing reverse spread of the reception input by using the orthogonal sinusoidal wave, thereby completely isolating the multi-user component including the multi rate.
