Abstract
Provided are methods and apparatuses to encode portions of user data with corresponding spreading sequences within a frame wherein the user data is associated with a single user.
Claims19
A method of transmitting data on a link from a first radio to a second radio across a plurality of timeslots in a frame, the method comprising:
- associating a first portion of user data with a first portion of the frame;
- associating a second portion of user data with a second portion of the frame;
- encoding the first portion of user data with a first spreading sequence;
- encoding the second portion of user data with a second spreading sequence, wherein the first spreading sequence differs from the second spreading sequence;
- transmitting, from the first radio to the second radio, the encoded first portion of user data in the first portion of the frame;
- and
- transmitting, from the first radio to the second radio, the encoded second portion of user data in the second portion of the frame.

A code diversity transmitter comprising:
- logic to accept user data;
- code mapping and distribution logic, wherein the code mapping and distribution logic is operable to parse user data into a first portion of user data and a second portion of user data;
- encoding logic operable to encode the first portion of user data with a first spreading sequence and operable to encode the second portion of user data with a second spreading sequence different from the first spreading sequence;
- and
- a transmitter coupled to the encoding logic and operable to transmit encoded user data.
