Dual Square-Shaped Constellation With Two-Layer Coding and Successive Demapping for Odd-Bit QAM

Odd-bit quadrature amplitude modulations (QAMs) can achieve higher data rates than even-bit QAMs in some signal-to-noise (SNR) regions but they have not been used in wireless communication standards due to its high demapping complexity. In this paper, we propose a novel constellation for odd-bit QAM...
