摘要:
Transferring spectrum use rights may include ascertaining information regarding available spectrum for use in wireless communications. A request for spectrum use from a spectrum user system may be matched with available spectrum. A spectrum certificate may be issued to the spectrum user system, where the spectrum certificate contains at least one spectrum-related variable under which the spectrum user system is to engage in wireless communications.

A method and system for directly down-converting FM signals to demodulated baseband information signals that can be used to directly down-convert analog FM signals and digital FM signals to demodulated baseband information signals. In an embodiment, the method includes aliasing an FM signal at an aliasing rate substantially equal to the frequency of the FM signal or substantially equal to a sub-harmonic thereof; adjusting the aliasing rate in accordance with frequency changes on the FM signal to maintain the aliasing rate substantially equal to the frequency of the FM signal, and outputting a demodulated baseband information signal. The method optionally includes compensating for phase delays and/or other characteristics of the loop in order to maintain bandwidth and stability for the loop.

摘要:
Systems and methods for planning a wireless network are disclosed. Attributes of the wireless network may be determined from minimal information. For instance, based on a specified coverage area and network usage information, and without operating frequency information, base station equipment models may be determined. An estimated number of base stations to deploy the network also may be determined. Also, a geographic extent of the network for regulatory compliance and acquisition of spectrum use rights may be determined.

Frequency translation and applications of same are described herein, including RF modem and wireless local area network (WLAN) applications. Such applications include, but are not limited to, frequency down-conversion, frequency up-conversion, enhanced signal reception, unified down-conversion and filtering, and combinations and applications of same.
摘要:
The present invention is directed toward the transmission subsystem of a multi-mode, multi-band communication system that can transmit and/or receive one or more information signals on one or more transmission frequencies using one or more modulation schemes. According to embodiments of the invention, the up-conversion section is implemented using a universal frequency translator (UFT).
