| 英文摘要: |
| Power line communication (PLC)has the potential to become the preferred technique for providing broadband communication to homes and offices with advantage of eliminating the need for new wiring infrastructure and reducing the cost. But it suffers from the impulsive noise because it introduces significant time variance into the power line channel. In this paper, a polar codes based or thogonal frequency division multiplexing (OFDM)PLC system is proposed to deal with the impulsive noise and thereby improve the transmission performance. Firstly , the impulsive noise is modelled with a multi-damped sine function by analyzing the time behavior of impulse events. Then the polar codes are used to combat the impulsive noise of PLC channel, and a low complexity bit-flipping decoding method based on CRC-aided successive cancellation list (CA-SCL)decoding algorithm is proposed. Simulations evaluate the proposed decoding algorithm and the results validate the suggested polar codes based OFDM-PLC scheme which can improve the BER performance of PLC with impulsive interference. |
