doc.: IEEE /0706r2 Submission Comments For short delay spread channels, AWGN And Exp 4ns, CE of all schemes has enough accuracy (required SNRs are within 0.1 dB difference) For long delay spread channels, schemes 2 and scheme 3 CE provides enough accuracy, and adding more Z256 sequences provides little performance gain Sign inversion of Z256 sequences does NOT cause any significant performance loss May 2015 Slide 27 Frank Hsu (MediaTek)
