The first-order (FO) perturbation theory-based nonlinearity compensation (PB-NLC) technique has been widely investigated to combat the detrimental effects of intra-channel Kerr in polarization-multiplexed (Pol-Mux) optical fiber communication systems. However, NLC performance FO-PB-NLC is significantly limited highly nonlinear regimes Pol-Mux long-haul transmission In this paper, we extend FO t...

A multiplexed Cassegrain reflector antenna with a 2 × 2 open-ended rectangular waveguide (OERW) matrix feed and an orbital angular momentum (OAM) mode mux is proposed for the simultaneous generation of three OAM modes (l = 0, ±1). The OAM mode mux (OMM) was designed using sequential combinations of quadrature hybrids, crossovers, and phase shifters to multiplex and demultiplex three OAM modes a...

This paper presents a new cell matching method which could be effectively used for MUX-based FPGA technology mapping. In this method, a well organized cell library of a manageable size is constructed for each target architecture a priori, and cell matchings are performed by searching the corresponding entry in the library using integer comparison operations. Experimental results for some MCNC b...

If 4-20 mA is used, make sure to specify 4-20 mA AI and AO cards which support native HART “pass-through”. Thus separate HART multiplexer (MUX) hardware and associated integration work is not required. Native HART pass-through AI and AO cards are much easier to integrate. HART communication is too slow for control, but is passed through to the IDM software. Be wary of proprietary smart protocol...

Previous efforts to reduce SRAM power have included voltage scaling to the edge of sub-threshold [2] or into the sub-threshold region [3], but only for idle cells. Although some published SRAMs operate at the edge of sub-threshold, none function at sub-threshold supply voltages compatible with logic operating at the minimum energy point. The 0.18μm memory in [4] provides one exception. Consisti...

This paper proposes a solution for extending the availability of transparent high-speed Ethernet by re-using the existing T1/E1 TDM network. By employing inverse multiplexing technology with support for jumbo Ethernet frames, service providers can use bonded T1/E1 circuits to transparently backhaul Ethernet from remote cell sites and IPDSLAMs. This paper covers the rationale, protocols and key ...
