- Abstract
- We introduce Yarg code, a binary numeral system for QAM symbol mapping designed to yield improved physical layer security. The simulation results show that Yarg code reduces the security gap from 17.33 dB to 9.42 dB for 16 QAM, and from 17.7 dB to 7.18 dB for 64 QAM with respect to the Gray code. The improved security properties come at the cost of increased required SNR by 6-9 dB. © 2009 IEEE.
