Patent number: 8694037Abstract: Method for optimizing the delay spread performance of a radio receiver (200) includes evaluating (306) a delay spread environment to determine if a desired RF signal is being received under conditions of low delay spread or high delay spread. If a low delay spread condition, the baseband digital data signal is filtered using a narrow filter (310).

The center frequency of the wide bandwidth filter is selectively shifted (316, 320) in accordance with a predetermined frequency offset if a second received power level of an interfering signal in an adjacent channel exceeds the first received power level by a predetermined threshold amount. This frequency shift of the filter allows for improved delay spread performance while minimizing any performance degradation when an interfering signal is present on an adjacent channel.Type: GrantFiled: February 7, 2013Date of Patent: April 8, 2014Assignee: Harris CorporationInventor: Mac L.

Patent number: 8526985Abstract: An application server in a communication network receives a plurality of data streams from a plurality of mobile stations that include a client for the application server. The data streams may be video, audio or a combination thereof and include an indicator of originating location of the data stream. A subset of the plurality of data streams that originates from an area are determined. The first set may also be determined based on a tag that is included in each of the data streams of the first set, the tag indicating a sharing status for a respective data stream and/or a subject of the respective data stream. A first data stream of the first subset transmitted to a service subscriber having an interest preference corresponding to the tag of first set data streams. The transmitted first data stream may include overlay content associated with the service provider.Type: GrantFiled: December 17, 2009Date of Patent: September 3, 2013Assignee: Alcatel LucentInventors: Bruce R. Cilli, Charles Payette, Narayan Raman

Patent number: 8521083Abstract: The time synchronization system according to the present invention can allow the master and slave time Tx/Rx devices to communicate information therebetween via two-way interactive wireless communication, so that it can rapidly detect an error that occurs in the system, via a monitoring device and a network management device for performing real-time integral management. Therefore, the system can reduce the user's system maintenance fee and can also maximize efficiency. In addition, the time synchronization system can allow for the easy extension of the equipment construction coverage area even in a long distance environment, by installing only repeaters, and can manage log information that may be used as evidence data for various incidents.Type: GrantFiled: December 24, 2010Date of Patent: August 27, 2013Assignee: Hook and Time Co., Ltd.Inventors: Young Seok Lee, Kwang Sung Jeung

Patent number: 8514837Abstract: There is elucidated a method of communicating data packets (210; 520) within a data communication network (10). The network (10) comprises communication nodes (30a, 30b, 30c, 40), wherein a first nodal set (30a, 30b, 30c) comprises nodes which are operable to communicate via a communication medium with a second nodal set (40) comprising at least one of said nodes (30a, 30b, 30c, 40). The method comprises steps of: (a) mutually synchronizing together two or more nodes of said first nodal set; and (b) simultaneously in a synchronized manner transmitting one or more data packets from the mutually synchronized two or more nodes of said first nodal set via said communication medium for substantially simultaneous reception at said second nodal set (40).Type: GrantFiled: June 12, 2007Date of Patent: August 20, 2013Assignee: Koninklijke Philips N.V.Inventors: Xiangyu Wang, Yonggang Du

Patent number: 8515471Abstract: A method and system for sending the same data in multiple directions via directional transmission is disclosed. One embodiment of the invention allows for processing power to be saved by introducing a buffer in the physical (PHY) layer, after some baseband (BB) processing has been performed. In one embodiment of the invention the method comprises receiving data from a MAC layer, performing preliminary processing on data in the PHY layer, storing the preliminarily processed data in a buffer located in the PHY layer, performing secondary processing on the preliminarily processed data, transmitting the secondarily processed data in a first direction, via directional transmission, reading the preliminarily processed data from the buffer, performing secondary processing on the preliminarily processed data, and transmitting the secondarily processed data in a second, third, fourth and so-on direction.Type: GrantFiled: February 15, 2008Date of Patent: August 20, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Huai-Rong Shao, Chiu Ngo

Patent number: 8509830Abstract: Data is synchronized between a mobile device and a computing device over a wireless link. Synchronization operations are scheduled according to a synchronization schedule that is based on a current time of day. In one embodiment, the day can be divided into different time periods by the user. The user can also specify the frequency with which synchronization operations are to be performed during each specified period.Type: GrantFiled: February 9, 2012Date of Patent: August 13, 2013Assignee: Microsoft CorporationInventors: Sandra L. Vargas, David R. Williamson, Gary W. Hall, Michael A. Foster, Juan V. Esteve Balducci

Patent number: 8498360Abstract: Advantage is taken of adaptive allocation techniques by intentionally creating multi-user diversity in an otherwise flat fading environment in order to improve system capacity. In one embodiment, multi-path distortion can be resolved to determine subscriber station (SS) diversity gain. Overall network capacity can be increased by allocating channel assignments to SSs within the network based on determined SS diversity gains. In one embodiment, intentional multi-path distortion is produced by transmitting a signal and a time-delayed version of the signal from a base station (BS).Type: GrantFiled: August 23, 2010Date of Patent: July 30, 2013Assignee: Adaptix, Inc.Inventors: Manyuan Shen, Guanbin Xing
