Abstract

En 中文

The artificial noise (AN) aided channel quality indicator (CQI) mapped generalized spatial modulation (GSM) philosophy is proposed for improving the security of legitimate links. Given the randomness of the legitimate CQI, eavesdroppers cannot successfully decode the confidential information. We analyse both the secrecy rate as well as the eavesdropper's error rate and reveal that the proposed scheme outperforms its CQI-mapped modulation counterpart. Theoretically, the secrecy rate approaches the achievable data rate of the legitimate link, which is equal to the GSM capacity.
