All colorless Fabry–Perot laser diodes (FPLDs) with master-to-slave injection-locking and carrier-reusing are employed as down- and up-stream transmitters to demonstrate the bidirectionally 10-Gbit/s full-duplex on–off-keying transmission in a dense wavelength-division-multiplexed passive optical network system without using any high-coherent transmitter. By simply injecting the down-stream optical...
The IEEE 802.16m standard is developed to support advanced services with high data rate and high mobility for the next generation broadband wireless access networks. A novel sleep mode operation is specified in the standard to conserve the energy of mobile devices. In this paper, a concise analytical model for the sleep mode operation of the IEEE 802.16m is proposed. The effects of both downlink and...
Based on the use of space-filling curves, a broadband microstrip-fed slot antenna is proposed. Broad-band performance is achieved through merging different downscaled versions of a composition of “island-like” space-filling slot antennas without increasing the overall antenna size. This technique provides different resonant slot lengths corresponding to a wide range of frequencies. By merging three...
