A fully integrated CMOS direct-conversion 5 GHz transceiver is implemented in a 0.18 /spl mu/m digital CMOS process and housed in an LPCC-48 package. This chip, along with a companion baseband chip, provides a complete 802.11a solution covering all of the world-wide 4.92-5.845 GHz bands. The receiver achieves a 3.5 dB NF while the transmitter achieves a +23(More)
In Wireless Sensor Networks (WSNs), most studies define a common duty cycle value throughout the network to achieve synchronization among the nodes. On the other hand, a few studies propose adaptation of the duty cycle according to uniform traffic conditions to decrease the energy consumption and latency. In this paper, the lifetime of the node based on(More)
Wireless measure while drilling (MWD) transmits data by using mud pulse signal ; the ground decoding system collects the mud pulse signal and then decodes and displays the parameters under the down-hole according to the designed encoding rules and the correct detection and recognition of the ground decoding system towards the received mud pulse signal is(More)
