The proposed frequency band for a 4G mobile system is 2 to 8 GHz, while the proposed access for the system is MC-CDMA / OFDM. In this paper, a new access technique has been proposed, with the bandwidth of the system divided into ten sub-bands. Each sub-band has40 channels and the access is a multi-band of the carrier CDMA (MBC-CDMA). The proposed access… (More)
Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) are two important wireless technologies that have variety of applications and provide unbounded future potentials. However, RFID and sensor networks nearly are under growth in similar way. Integration of RFID and wireless sensor networks attracts little attention from research… (More)
