Abstract :
High-speed data communications appear to be very important for home networks (HN). The work presents a scheme of orthogonal frequency division multiple access (OFDMA), which is based on large area synchronous codes (LAS-codes) with an interference free window (IFW). Such a scheme is employed in power line carrier (PLC) communications to increase data throughput, system capacity and spectral efficiency in HN.
