Patent ID: 7039243

Claim:
An apparatus for encoding information represented by at least first and second data items, said apparatus comprising: a memory that stores data associated with a reference signal complex, the reference signal complex including at least first and second spectral components having first and second frequencies, respectively, the first and second frequencies being different, the first and second spectral components having first and second reference parameters, respectively; an input that receives the first and second data items; a processor executing a set of programmed instructions for adjusting the first reference parameter of the first spectral component of the reference signal complex in accordance with the first data item and for adjusting the second reference parameter of the second spectral component of the reference signal complex in accordance with the second data item, the processor further forming an encoded signal complex including at least the adjusted first and second spectral components; and an output that is adapted to communicate the encoded signal complex to another apparatus external to the encoding apparatus.
