    摘要： The present invention relates to a field of computer application technology, and more particularly to a computer account management system and a realizing method thereof. The computer account management system includes: an account management subsystem; an information asset management subsystem; an authentication (integrated) subsystem; a service (integrated) subsystem; and an account portal subsystem; wherein the account management subsystem manages information of physical accounts and logical account numbers; wherein the information asset management subsystem manages data information resources generated by network activities of physical account information; wherein the authentication subsystem provides an authentication integrated interface to the physical account numbers; wherein the service subsystem is a customizable interface which is open to internet or local network; wherein the account portal provides interfaces and tools of login, service list management of services subscribed or bought by the account, account information management and information asset management. The present invention provides a universal computer account system which is not bundled with the service, seamlessly integrated with the user information asset and is lifetime-valid. The system can be used in account management of the internet.

    摘要： A radio frequency to digital receiver has a modulator sampling a signal at a first rate. The receiver has at least one processing unit. The processing unit has a plurality of digital bandpass filters separating the signal and recombining the signal at a rate less than the first rate. The processing unit has a digital down converter adjusting frequency offset or centering the signal at the rate less than the first rate. The receiver has at least one rate control buffer coupled to adjacent processing units when two or more processing units are within the receiver.

    摘要： A calibration system for an RF system that includes an RF receiver capable of operating in a normal mode and in a calibration mode. The calibration system includes a phase delay unit provided on at least one of an I channel output and a Q channel output of the RF receiver. The system further includes a phase detector configured to detect a phase difference between the I channel output of the RF receiver and the Q channel output of the RF receiver. The system also includes a calibration control unit configured to provide a digital calibration control signal to the RF receiver based on the phase difference as provided by the phase detector.
