Transmitting data via varying transmission rate several links involves providing mutually orthogonal spreading codes for spreading data to be transmitted, at least two codes for scrambling spread data

摘要

The data transmission method involves providing mutually orthogonal spreading codes for spreading the data (D1,D2) to be transmitted and at least two scrambling codes for scrambling the spread data. The spreading and scrambling codes are used in alternative combinations with data groups (G11,G12) to achieve first and second transmission rates on the connections (V1,V2). An independent claim is included for a station for a communications system for transmitting data via several links with varying transmission rates.
