A new Communication protocol design in the Data Link Layer of the industry Ethernet ring network is presented in this paper. The HDL files used in the design are packaged into IP Core. The simulation shows that the MAC protocol design for the Industry Ethernet Ring Network can send and receive not only the special frames of the Industry Ethernet ring network but the frames of the traditional Ethernet...
In this paper, a UWB multiple-input-multiple-output (MIMO) antenna is proposed for a 4G Mobile Phone. It consistes of two differential antennas which are perpendicular to each other, and covers TD LTE, some of GSM, WCDMA and FDD LTE bands. The magnitudes of the isolation values S21 and S12 are lower than-15 dB at all frequencies in the domain, and theoretically there isn't any coupling between the...
