Title:
BIT TO SYMBOL MAPPING DESIGN FOR BIT-LEVEL CONSTELLATION SHAPING
Document Type and Number:
WIPO Patent Application WO/2024/045151
Kind Code:
A1
Abstract:
The apparatus may be configured to process input information including a set of information bits for a quadrature amplitude modulated (QAM) transmission by performing a bit-shaping operation for the set of information bits to generate a set of shaped bits and adding cyclic redundancy check (CRC) bits before forward error correction (FEC) on a combination of the set of information bits and the CRC bits. The apparatus may further be configured to transmit the QAM transmission. The apparatus may be configured to receive a QAM transmission; perform a FEC decoding on the QAM transmission; obtain CRC bits from the QAM transmission after the FEC decoding; and perform a bit level de-shaping operation on a set of shaped bits to obtain a set of information bits.
