We proposed a pre-compensation method combining two wireless communication schemes, TDD(Time Division Duplex) whose forward and reverse links use the same frequency, and the coher...
—In the next generation mobile communication systems, high-speed and high-quality packet data services are demanded. Hybrid ARQ (HARQ) is known as one of the promising error cont...
— Placing relays around the base station (BS) to assist wireless communication is an effective way of extending coverage in cellular systems. This paper provides a quantitative a...
Emerging pervasive computing technologies such as sensor networks and RFID tags can be embedded in our everyday environment to digitally store and elaborate a variety of informatio...
Movement in wireless and sensor environments changes the degree to which we can communicate. Whereas sensor networks are generally seen as static, in many situations there is at l...
