A Random Subcarrier-Selection Method Based on Index Modulation for Secure Transmission

A Random Subcarrier-Selection Method Based on Index Modulation for Secure Transmission

Recently, a frequency diverse array (FDA) has been employed in an orthogonal frequency division multiplexing (OFDM) transmitter to achieve secure wireless communication without mathematical encryption. However, an insecure coupling effect arises if the frequency increments are linearly assigned to a...
