(A scheme and termination method of the frame structure of the medium access control (MAC) layer under a specific link bit error rate are proposed. In the process of the MAC frame scheme, the frame length is determined through Matlab simulation, and the fields in the MAC frame are analyzed; and the detailed termination of the MAC frame is based on the FPGA chip XC5VFX70T of Xilinx Enterprise. The data includes the following attachments :)
