Abstract |
This paper proposes a random coded data protection technique in space-time block code. The traditional space-time block coding technique could be faced with open radio environments, so it has to overcome severe radio hijacking problems. In case of trying to avoid open radio issue, usually source data blocks are encrypted but it occurs heavy burden to the transmitter and receiver. This paper proposes a simple random coded timing sequence of data blocks, its effect results in received signals' exchange during consecutive time blocks and source data are exchanged also. This kind of combining method in space-time block coding technique could be an encryption technique to neighboring receivers. Simulation results show that the proposed algorithm has a better performance in comparison to the receivers of not knowing the timing sequence of sign reversal. |
