摘要： This invention involves with a low power IC (Integrated Circuit) with high energy efficiency. This invention describes a Buck converter that can track the minimum energy point of the load. It works by estimating input energy of every sensing period, taking advantage of energy consumption curve of IC in sub-threshold. Energy estimation is implemented with counting conducted pulses, while maintaining constant input energy of each pulse by regulating output voltage and ON time with digital control circuit. With digital control circuit, minimum energy point can be tracked with a lookup table stored inside. Most of this invention's control circuit is digital, with benefits of low power consumption and small chip area.

摘要： Provided is a modulation device which generates a phase modulation signal and an amplitude modulation signal and can correct an I/Q orthogonal shift and reduce degradation of the ON/OFF ratio. In the device, a phase shifter (174) controls voltage applied to a capacitor in accordance with a control signal outputted from a phase control unit (180) and adjusts the capacitance so as to shift the phase of a carrier generated by an oscillator (173). The phase control unit (180) estimates a phase shift of a phase shifter (174) in accordance with an output RF signal (S140) by using the phase shift estimation method. Furthermore, the phase control unit (180) performs tuning of the phase shifter (174) according to the estimated value of the phase shift of the phase shifter (174) so that a phase difference between carries of an I signal (S125) and a Q signal (S135) is 90 degrees.

摘要： The teachings of the present disclosure relate to a method for receiving “N” data streams (wherein “N” is a number greater than one) from “N” endpoints. Each of the data streams are received from a different respective endpoint. The method also includes decoding the “N” data streams by generating a decoding signal input comprising the “N” data streams and then iteratively repeating the following steps “N”−1 times: determine a most reliable stream; decode the most reliable stream using linear multiple-input and multiple-output (MIMO) decoding; output the decoded most reliable stream; estimate a signal estimate based on the most reliable stream and modulation information associated with the most reliable stream; and generate a residual signal that comprises the remaining data streams less the signal estimate. Upon the residual signal comprising two data streams, the method includes updating the decoding signal input to be the residual signal. Upon the residual signal comprising a single received stream, the method includes decoding the residual signal using a maximum likelihood decoder.

摘要： The client portion of a distributed client-server network management system uses an interface designed with, and written in, a platform independent language, such as Java. This allows management application programs to be written in the platform independent language and insures their portability. The inventive interface caches most of the management information at the server so that only a small client program is necessary. This program can run on a system with minimal resources, thereby allowing a network manager to manage a network from virtually any location on the network. For example, the client management application could be written as a Java applet which could then be run on any Java-enabled browser. The inventive distributed management system can also connect with, and use, the services and structure of existing distributed network management systems.
