Abstract
A tone map selecting device includes: a bit-number-per-symbol providing circuit, providing a plurality of bit numbers per symbol, each of which associated with a tone map; a calculating circuit, performing a predetermined calculation on the bit numbers per symbol to generate a calculation result; and a selecting circuit, identifying one of the bit numbers per symbol that satisfies a predetermined relationship with the calculation result, and selecting the tone map associated with the bit number per symbol satisfying the predetermined relationship as a default tone map.
Claims12
A tone map selecting device, comprising:
- a bit-number-per-symbol providing circuit, providing a plurality of bit numbers per symbol, each of which associated with a tone map;
- a calculating circuit, performing a predetermined calculation on the plurality of bit numbers per symbol to generate a calculation result;
- and
- a selecting circuit, identifying one of the plurality of bit numbers per symbol that satisfies a predetermined relationship with the calculation result, and selecting the tone map associated with the bit number per symbol satisfying the predetermined relationship as a default tone map.
A tone map selecting method, applied to a signal receiver of a power line communication (PLC) system, comprising:
- obtaining a plurality of bit numbers per symbol, each of which associated with a tone map;
- performing a predetermined calculation on the plurality of bit numbers per symbol to generate a calculation result;
- and
- identifying one of the plurality of bit numbers per symbol that satisfies a predetermined relationship with the calculation result, and selecting the tone map associated with the bit number per symbol satisfying the predetermined relationship as a default tone map.
