Method and apparatus for digital representations of analog signals and control words using different multi-level modulation formats

摘要

A method implemented by a transmitter, the method comprising: encoding digital in-phase and quadrature-phase (IQ) data associated with a plurality of analog signals in accordance with a first multi-level modulation format to produce a modulated IQ signal Encoding the control information associated with the plurality of analog signals according to a second multi-level modulation format that is different from the first multi-level modulation format to generate a modulated control signal, the modulated IQ signal and the modulated Aggregating control signals via time-division multiplexing (TDM) to generate an aggregated TDM signal, and transmitting the aggregated TDM signal over a communication channel.
