Fine step blended modulation communications
First Claim
1. A communication device comprising:
- a communication interface; and
a processor, at least one of the processor or the communication interface configured to;
select a blended modulation from a plurality of blended modulations based on a desired energy per bit to noise spectral density ratio (Eb/N0) or symbol to noise spectral density ratio (Es/N0), wherein each of the plurality of blended modulations has a different respective energy per bit to noise spectral density ratio (Eb/N0) or symbol to noise spectral density ratio (Es/N0) than other of the plurality of blended modulations, wherein the blended modulation is a combination of at least two modulations, and wherein each of the at least two modulations includes a respective set of bit labels for a respective set of constellation points therein;
map a plurality of bits to the blended modulation to generate a modulation symbol; and
transmit the modulation symbol to another communication device.

Abstract
A communication device is configured to perform symbol mapping of bits to generate modulation symbols using one or more modulations. The device may employ a blended modulation composed of bit labels or symbols having different numbers of bits per symbol and different modulations. For example, the device may symbol map bit labels/symbols having first number of bits per symbol to first modulation, and the device may symbol map labels/symbols having second number of bits per symbol to second modulation. The device may be configured to perform forward error correction (FEC) or error correction code (ECC) and coding of information bits to generate coded bits that subsequently undergo symbol mapping. The device may be configured to operate based on different operational modes based on substantially uniform steps of rates, or bits per symbol, and energy per bit or symbol to noise spectral density ratio (Eb/N0 or Es/N0).
