DATA BLOCK SPREAD TYPE SPECTRUM SPREAD COMMUNICATION METHOD

摘要

A data-block spread spectrum communications system which produces a data-block consisting of plurality M bits of transmit-data in a CDMA communications system, transmits spread symbols each of which is made by modulating an orthogonal sine wave with a repeated sequence of said data-block, and de-spreads a received input using said orthogonal sine wave to completely separate and distinguish respective multi-user multi-rate components.
