Adaptive impedance matching system for broadband power line communication using RC-filters

The broadband power line communication (BPLC) is designed under severe propagation constraints with devices of low cost, which provides integrated operation with other such devices, mainly the spatial and temporal variation of input side impedance. Adaptive impedance matching circuits have been proposed in this study, and most are designed for BPLC. The range of operating frequency and various proposals of impedance matching techniques are studied, and a new structure of the circuit is introduced. The impedance mismatch between the transmission line and the recipient reduces the signal-to-noise-power ratio at the receiver. A fixed matching circuit will be wasteful when the access impedance fluctuates. In other words, the system suggested in this paper offers a mechanism for adaptive improvement that best matches the transmission and receipt of signal flows. The system is assessed using simulations for various access impedance test sites and S-parameters of BPLC networks. Our simulation results showed that, within 20% of the theoretical optimum, the adaptive matching method presented could match signal power transfer. This corresponds to up to ten times higher power than other literary solutions. Motivation: Increasing demand for broadband signal in different media viz audio, video/image, and the internet has led to the development of wireless/wireline technology processing with a high growth rate. Advanced signal processing techniques now enable megabits per second to be carried over this extremely hostile channel, viz residential power wiring. There is a shortfall in data rate if the load is inductive in BPLC. Although there are many impedance matching techniques, one of the most significant complications they face is their static nature, i.e., they are designed to match a particular load. Contribution: The matching circuitry and sensor and control unit for the adjustment of circuit components is part of an adaptive impedance system. The technique suggested achieves a signal transmission close to an optimum match. The overall power transfer increases are reached by up to 10 dB.
