A Simulation-Based Fixed Point Algorithm in Rural Distribution Line Communication

The noise on the rural distribution line communication is mainly generated by the electrical equipment connected to the power line. It has a certain degree of influence on the communication system. The accuracy requirement of the system to the output of the signal is becoming increasingly high. How to improve information transmission method and efficiency of the rural distribution line communication is a key issue of the current power industry. The blind source separation technique, theory characteristic and the related model are discussed. Using fixed point algorithm (FastICA) to eliminate noise on the rural distribution line communication signal is researched. A variety of mixed-signal separation is simulated by the fixed point algorithm. The experimental results are analyzed. The blind signal separation technology used in the rural distribution line communication system has theoretical basis and feasibility of practical application.
