We recently proposed high-order circular quadrature amplitude modulation (QAM) constellation using partial low-density parity-check (LDPC) code aiming at the application to wireless microwave backhaul. This paper presents peak-to-average power ratio (PAPR) performance of circular 1024QAM, 2048QAM, and 4096QAM constellations based on our proposed design method, and compare them with those rectangular 1024QAM, cross 2048QAM, and rectangular 4096QAM, respectively. We also present the corresponding bit error rate (BER) performance of these circular QAM constellations using partial LDPC coding with parallel double Gray mapping. Computer simulation results show that the circular QAM constellations achieve equal or lower PAPR compared to that of the corresponding rectangular or cross QAM constellation with the same frequency efficiency. Therefore, we conclude that high-order circular 2k QAM constellation (k is an integer) based on the proposed design method is more advantageous in decreasing the PAPR as well as achieving the better BER compared to the rectangular QAM constellation when using partial LDPC coding with double Gray mapping. |
