| 摘要: |
| 提出了一种将电力线信道状态映射为服务质量（QoS）参数的方法，该方法将实际的电力线信道状态参数通过数学推导等效为相关QoS参数，包括时延、信道容量、误码率（BER）、时延抖动。由QoS参数决定电力线信道是否满足业务传输需求。依据所提方法建立了在特定条件下的P2P电力线通信仿真系统，仿真结果验证了所提方法的可行性和有效性。 |

| Abstract: |
| A method of mapping the PLC（Power Line Communication） channel status to the QoS（Quality of Service） parameters is proposed，which applies the mathematical derivation to make the PLC channel status equivalent to QoS parameters，such as time delay，channel capacity，BER（Bit Error Rate） and delay jitter. The obtained QoS parameters are then used to determine whether the PLC channel satisfies the requirements of service transmission. A simulation system of P2P PLC in specific conditions is established based on the proposed method and the simulative results show its feasibility and effectiveness. |
