Product coded modulation scheme based on leech lattice and binary and nonbinary codes

摘要

A transceiver architecture contains an encoder and a decoder for communicating high speed transmissions. The encoder modulates signal data based on an FEC code that has a symbol size that is not matched to a symbol size of a hexacode. Any code where the symbol size is less than the sample size for coding can be serially concatenated. During decoding the multilevel decoding leech lattice and FEC decoder iteratively passes their outputs back and forth to each other until the encoded bits are decoded.
