- Abstract
- In conventional bit-to-symbol mapping for θQAM, the Hamming distance between the symbols with the minimum Euclidean distance is not minimized when θ < 60°, and this undesirably increases the bit error rate (BER). In this paper, we propose an enhanced bit-to-symbol mapping for M-ary θQAM, which minimizes the Hamming distance between the symbols with the minimum Euclidean distance even when θ < 60°. By adopting the conventional mapping when θ ≥ 60° and the proposed mapping when θ < 60°, we formulate the overall bit-tosymbol mapping for θ-QAM. To validate the proposed bit-tosymbol mapping, we compare the BERs of the proposed mapping and the conventional one through computer simulations.
