Non-Uniform • IEEE 802.11a/n/ac use Uniform constellations for QPSK, 16QAM, 64QAM and 256QAM – Some hardware can be re-used for Uniform 1024QAM • Uniform 1024QAM constellations have been adopted in Digital Subscriber Line (DSL) and Passive Optical Network (PON) standards. • Less complexity for uniform 1024QAM constellation. • The gain provided by Non-uniform constellation is not significant – 0.3dB gain is claimed in [1] • Uniform 1024QAM constellation is more suitable for ML demodulation using sphere decoder. Submission May, 2016 doc.: IEEE 802.11-16/0656r1 Normalization factor for 1024QAM • The normalization factor for 1024QAM is: K mod 1 / 682 • Reference codes for 1024QAM modulation: SymShape = reshape(Data,BitsPerSC,Ndsc,NumSyms); Kmod=1/sqrt(682); table = [-31 -29 -25 -27 -17 -19 -23 -21 -1 -3 -7 -5 -15 -13 -9 -11 31 29 25 27 17 19 23 21 1 3 7 5 15 13 9 11]; % gray encoding DataReal = squeeze(SymShape(1,:,:)*16 + SymShape(2,:,:)*8 + SymShape(3,:,:)*4+SymShape(4,:,:)*2+SymShape(5,:,:)) + 1; DataImag = squeeze(SymShape(6,:,:)*16 + SymShape(7,:,:)*8 + SymShape(8,:,:)*4+SymShape(9,:,:)*2+SymShape(10,:,:)) + 1; FDreal = table(DataReal); FDimag = table(DataImag); if NumSyms>1 FDdata = Kmod*(FDreal + j*FDimag).'; else FDdata = Kmod*(FDreal + j*FDimag); end Submission May, 2016 doc.: IEEE 802.11-16/0656r1 Simulation • • • • • • Submission 2x2 MIMO MCS-10 & MCS-11 BCC & LDPC AWGN, D-NLOS, B-NLOS Ideal CE Packet length = 1000B; 500 runs May, 2016 doc.: IEEE 802.11-16/0656r1 Uniform 1024QAM: ZF vs. MLD 242-RU,MCS10,B-LOS,LDPC,pktlen = 1000B, 500pkts, 2x2 0 10 PER MLD ZF -1 10 -2 10 32.5 33 33.5 34 34.5 35 35.5 36 36.5 37 37.5 SNR(dB) MLD achieves more than 11dB gain than ZF for Uniform 1024QAM at 10%PER Submission May, 2016 doc.: IEEE 802.11-16/0656r1 Uniform vs. Non-Uniform Performance Gain (dB) of NUC over UC Simulation Condition MCS Channel Nss Phase-Noise (PN) 10% PER MCS10 AWGN 1 off 0.5 MCS10 AWGN 1 on 0.53 MCS10 D-NLOS 1 off 0.49 MCS10 D-NLOS 1 on 0.51 Performance Gain (dB) of NUC over UC Simulation Condition MCS Channel Nss Phase-Noise (PN) 10% PER MCS10 AWGN 2 off 0.2 MCS10 D-NLOS 2 off 0.34 The gain provided by Non-uniform modulation is about 0.3dB in 2 spatial steams. Without efficient MLD for non-uniform 1024QAM modulation, Non-Uniform 1024QAM performs worse than Uniform 1024QAM with MLD. Submission May, 2016 doc.: IEEE 802.11-16/0656r1 Conclusion • We compared the performance of Non-Uniform and Uniform 1024QAM constellation. • We propose a Gray encoding based Uniform 1024QAM constellation mapping – Uniform 1024QAM constellation is consistent with other QAM mapping used in 11n/ac/ax; – Uniform 1024QAM constellation is well structured suitable for efficient implementation, especially for MLD; – More Hardware reuse for Uniform 1024QAM constellation .
