Abstract
Power line communications (PLC) has become a viable local area network (LAN) solution for in-home networks. PLC systems can be used in a wide variety of applications requiring high data rate. Therefore, there is a need to achieve an extremely high bit rate. In this paper, the increase in current technology bandwidth up to 100 MHz is investigated. Furthermore, a fast computational resource allocation algorithm is also developed for linear precoded discrete multitone (LP-DMT), which enables reliable high bit rate under peak BER constraint. Simulations are run over PLC channels and it is highlighted that 1 Gbit/s transmission is achievable and it is also shown that peak BER constraint algorithms give better performance compared to classical peak SER constraint algorithms. In addition, the linear precoding technique brings significant bit rate gain.
