1 Submission doc.: IEEE 802.11-15/0339r0 March 2015 Alecsander Eitan, QualcommSlide 1 SC 64APSK for 802.11ay Date: 2015-03-08 Authors:

2 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 2 Motivation and purpose 802.11ay goals are to extend the 11ad bitrate and performance At this time both SC and OFDM are considered for 11ay. In this presentation, we contribute to this goal by: Addition of 64 constellation to SC modulation to increase the bitrate of links that support only single channel SC (w or w/o channel bonding) Demonstrating the technical feasibility of achieving this goal Presenting simulation results Additional to the material presented in: 11-15-0094-00-ng60-SC 64QAM for NG60.pptx

3 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 3 Benefits of 64 Constellation Increase of 50% in PHY throughput or decrease of power consumption Increase spectral efficiency Benefit in dense environment Simple extension of existing modem

4 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 4 Mapping – straight forward extension Use standard 64QAM gray code mapping - same as OFDM mapping

5 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 5 64AQPSK – (developed by DVB-S2X) We tested various versions. DVB-S2X are highly optimized constellations We selected version is 8+16+20+20 with radiuses: [1, 2.2, 3.6, 5.0] 8+16+20+20APSK

6 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 6 Bit Mapping

7 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 7 PAPR 64QAM: Peak: 1.5275 PAPR: 3.68dB 64APSK Peak: 1.3655 PAPR: 2.71dB

8 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 8 64APSK Implementation Challenges Mapper and/or Tx Filter Slightly more complex than 64QAM but still manageable Demapper Looks much more complex than 64QAM LUT implementation is simple

9 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 9 Simulation Results

10 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 10 64QAM vs 64APSK

11 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 11 Performance of 64APSK with AWGN and PN

12 Submission doc.: IEEE 802.11-15/0339r0March 2015 Alecsander Eitan, QualcommSlide 12 Summary We suggest to add 64APSK to the SC modulation, with existing LDPC rates, as part of the 11ay Benefits: 50% throughput increase and increased spectral efficiency We are getting more confident that 64APSK SC is feasible
