Abstract:
A method for embedding a first signal in the coding of a second signal is described. A value of the first signal is determined. A codebook based on the value of the first signal is generated. A second signal is encoded using a codeword from the generated codebook. The encoded second signal is modulated into a plurality of symbols, wherein the symbols are distributed according to the value of the first signal. The modulated symbols are inserted into one or more time slots of a sequence.
