Method for Digital Cancellation of System Interference in a Full-Duplex Power Line Communication System

Every year the number of IoT devices is growing, which gives a boost to development such technology as Power Line Communication (PLC). The term PLC refers use power supply circuit transmit data. Full-duplex can be applied increase data transfer rate in PLC. difficulty using full duplex need suppress transmitter’s own signal (interference signal). Analog cancellation and digital are used for this purpose. Common algorithms adaptive algorithms. In paper Particle Swarm Optimization (PSO) Recursive Least Squares (RLS) considered modification classical RLS proposed. proposed algorithm uses precalculated weight coefficients together with periodic reinitialization filter. This avoids influence significant changes input on further process filter adaptation provides highest level echo suppression. an improvement parameters Error Vector Magnitude (EVM) Signal-to-Interference Ratio (SIR) comparison PSO, according results study.
