PRODUCT CODED MODULATION SCHEME BASED ON LEECH LATTICE AND BINARY AND NONBINARY CODES

摘要

A transceiver architectures can contain an encoder and a decoder for communicating high speed transmissions. The encoder can modulate 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 multi-level decoding leech lattice and FEC decoder can iteratively pass their outputs back and forth to each other until the encoded bits are decoded.
