Ber Performance

This paper aims to improve data security and BER performance in the Power Line Communication channel by using encryption and channel coding techniques. In particular, improvement in BER performance has been obtained while using OSTBC rather than STBC as compared to the results obtained in a previous work. The improved system has been extended to include data security in the PLC channel. In this respect, a Hybrid SDES-AES encryption scheme has been developed. The BER performance of the Hybrid SDES-AES encryption in the PLC channel has been improved by using Convolutional coding, Interleaving and OSTBC. A performance improvement of 11.8 dB has been obtained at a BER of 3×10−5 when compared with the Uncoded Hybrid Encryption case.
