Abstract
In accordance with embodiments, methods for data communications are disclosed. A device obtains a forward error correction (FEC) encoded bit stream. The device maps the FEC encoded bit stream to produce a set of symbols according to a bit-to-symbol mapping rule. The bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level. The first mapper error protection level is greater than the second mapper error protection level. The device then transmits the set of symbols in the communications system.
Claims19
A method comprising:
- obtaining, by a device, a forward error correction (FEC) encoded bit stream;
- mapping, by the device, the FEC encoded bit stream to a set of symbols according to a bit-to-symbol mapping rule, wherein the bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level, wherein the first mapper error protection level is greater than the second mapper error protection level, wherein the first mapper error protection level corresponds to a first minimum distance, and wherein the second mapper error protection level corresponds to a second minimum distance, the first minimum distance being greater than the second minimum distance;
- and
- transmitting, by the device, the set of symbols.
A transmitting device comprising:
- a bit-to-symbol mapper configured to:
- obtain a forward error correction (FEC) encoded bit stream;
- and
- map the FEC encoded bit stream to a set of symbols according to a bit-to-symbol mapping rule, wherein the bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level, wherein the first mapper error protection level is greater than the second mapper error protection level, wherein the first mapper error protection level corresponds to a first minimum distance, and wherein the second mapper error protection level corresponds to a second minimum distance, the first minimum distance being greater than the second minimum distance;
- and
- a transmitter configured to:
- transmit the set of symbols.
A device comprising:
- at least one processor;
- a non-transitory memory storing instructions that are executable by the at least one processor to cause the device to:
- obtain a forward error correction (FEC) encoded bit stream;
- map the FEC encoded bit stream to a set of symbols according to a bit-to-symbol mapping rule, wherein the bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level, wherein the first mapper error protection level is greater than the second mapper error protection level, wherein the first mapper error protection level corresponds to a first minimum distance, and wherein the second mapper error protection level corresponds to a second minimum distance, the first minimum distance being greater than the second minimum distance;
- and
- transmit the set of symbols.
