8086271 Network architecture for mobile communication network with billing module for shared resources December 27, 2011
A mobile communication network includes an antenna site shared by two or more telecommunications service providers. The antenna site includes a shared resource, such as an antenna, telecommunications equipment, or bandwidth, used by multiple service providers and connects to multiple
7623596 Methods and systems for estimating a channel response by applying bias to an initial channel est November 24, 2009
A channel response may be estimated from training symbols that are received over a channel, by determining an initial channel estimate from the training symbols and applying bias to the initial channel estimate to obtain a biased channel estimate. The biased channel estimate may then be
7616712 Systems and methods for detecting discontinuous transmission (DTX) using cyclic redundancy check November 10, 2009
A received information signal is decoded to obtain the received information and to produce at least one feature of the received information signal. The received information signal is preliminarily classified as containing a normal burst or a truncated burst based upon the at least on
7457263 Apparatus and method for channel request in a wireless communication system November 25, 2008
Apparatus and Method for Channel Request in a Wireless Communication System. The present invention provides a method to request channels in a wireless communication system in order to efficiently allocate channel resources by using channel function information about each transceiver. A
7440489 Method and apparatus for selective demodulation and decoding of communications signals October 21, 2008
A spread spectrum signal is processed by correlating the spread spectrum signal with a spreading sequence at a first plurality of correlation times to produce a first plurality of time-offset correlations. The first plurality of time-offset correlations is processed to produce a first
7418063 DTX detection method with high success probability August 26, 2008
A wireless communications system receiver classifies a received burst as a DTX-high state normal burst or a DTX-low state truncated burst with a high probability of success. D1, the Euclidean distance between the known CDVCC and the bit position of CDVCC in a normal burst, is determined
7409028 Clock synchronization in a communications environment August 5, 2008
A method and system provide a stable reference clock for use in a communication system. A phase-locked loop (PLL) receives an input clock signal with potentially unacceptable levels of jitter and wander. The PLL provides a synchronized output clock with significantly reduced jitter a
