Abstract

The method involves superimposing control channel on a user data channel within same nQAM constellation by binary data comprising both user data and control data. Separation of the control data is carried out by arranging control data points to have either unique phase, or unique amplitude, values which are not employed for user data points. The unique phase values fall on the boundaries between quadrants of a nQAM constellation. The user data points have phase values falling within the quadrants of the nQAM constellation.
