| 摘要: |
| 提出一种无线局域网中物理层与媒体访问控制(MAC)层的层间接口设计方案。该方案分别从硬件连线规划、地址分配、层间原语交互操作和层间数据收发等几个方面进行设计,并在FPGA上实现。通过一套完整的无线传输实验平台进行实验验证,结果表明,此接口功能符合IEEE 802.11a协议要求,物理实现简单,可扩展性好。 |

| Abstract: |
| A scheme is presented for designing the service interface between physical layer(PHY) and medium access control(MAC) in WLAN(wireless local area network) system.The hardware layout,register address allocation,primitives operations,and data intercommunication are designed in detail.The scheme is implemented based on FPGA and tested on a wireless transmission platform.The test results show that the service interface is compliant with the standard of IEEE 802.11a and has the advantages of simple implementation and good scalability. |
