Patent number: 9198172Abstract: The equipment and techniques disclosed herein introduce a deferred acknowledgement (DACK), in the context of a protocol for a wireless station to request and obtain access to a wireless network resource for communication of one or more data packets. Essentially, a network node, such as a wireless base station, sends the DACK instruction in response to the access request telling the requesting station that the node has heard the request but that the requesting station should defer its transmission. The requesting station need not back off and re-initiate its access request. Instead, the requesting station waits for a later acknowledgement (ACK) granting access to a resource as requested. Although the DACK provides additional signaling, this technique can still utilize a fast ACK type message, that is to say a relatively short signaling packet.Type: GrantFiled: October 27, 2014Date of Patent: November 24, 2015Assignee: GOOGLE INC.Inventor: Emmanuel Kanterakis

Patent number: 8718150Abstract: A disclosed code-division-multiple-access (CDMA) system has a base station (BS) and remote stations (RSs). A BS-spread-spectrum transmitter broadcasts a common-synchronization channel having a chip-sequence signal common to the remote stations served by the BS, and a frame-timing signal. A RS-spread-spectrum receiver receives the broadcast common-synchronization channel, and determines frame timing from the frame-timing signal. A first RS-spread-spectrum transmitter transmits an access-burst signal, which has a plurality of segments. Each access burst signal segment has a plurality of power levels. A BS-spread-spectrum receiver receives the access-burst signal at a detected-power level. In response to receiving the access-burst signal, a BS-spread-spectrum transmitter transmits an acknowledgment signal to the RS-spread-spectrum receiver.Type: GrantFiled: February 23, 2009Date of Patent: May 6, 2014Assignee: Golden Bridge Technology, Inc.Inventors: Emmanuel Kanterakis, Kourosh Parsa

Patent number: 8548026Abstract: An enhanced spread-spectrum uplink technique provides more efficient packet transfer in a wireless network. A mobile station requests to utilize an uplink channel, typically, a physical dedicated channel. If the network will grant access, a base station sends back a channel-request-granted message, which specifies a transmission start time and length. The base station starts related downlink transmissions at the start time, and at a time thereafter, the mobile station starts sending packet data over the uplink physical dedicated channel. After a transmission of no more that the specified length, the mobile station ceases its uplink transmission on the dedicated channel, and the base station and/or the mobile station can immediately release one or more channel resources. The grant message and/or the subsequent signaling communications from the base station may also specify a modulation scheme and a channelization code for the uplink channel.Type: GrantFiled: October 30, 2007Date of Patent: October 1, 2013Inventor: Emmanuel Kanterakis

Patent number: 8472863Abstract: The present invention has application to countering IEDs which are triggered remotely through a RF signal directed at, or the same operating environment as, receiver components embedded in, or part of, commercially manufactured cell phones or remote control devices. The invention exploits those situations where the underlying device (i.e., a commercial cell phone) is designed to operate in an environment where noise is characterized by an additive Gaussian noise model. The invention exploits the optimization of the matched filter for Gaussian noise by introducing a specific non-Gaussian noise. Further, the invention is directed to a family of jamming waveforms which exhibit increased effectiveness against a variety of digital and analog communications systems.Type: GrantFiled: December 10, 2008Date of Patent: June 25, 2013Assignee: Bank of America, N.A.Inventors: David Sheby, Emmanuel Kanterakis

Patent number: 7965237Abstract: The present invention provides a method by which the position of a wireless emitter can be estimated by using a minimum of two wireless transceiver devices. The invention relies on physically moving the wireless transceiver devices to new position locations in order to obtain multiple time difference of arrival measurements. The time difference of arrival measurements can then be combined to derive estimates for the position of the emitter. At least one of the two wireless transceiver devices needs to be mobile with the other one fixed. Using this invention, any proportion of mobile and fixed transceiver devices can be used to derive the position of a wireless emitter. The wireless emitter to be located is not assumed to provide any information about itself to the wireless transceivers used for estimating its position location. The method is referred here as a Mobile-TDOA method or M-TDOA.Type: GrantFiled: June 5, 2009Date of Patent: June 21, 2011Assignee: CACI Technologies, Inc.Inventor: Emmanuel Kanterakis

Publication number: 20060268717Abstract: A radio network controller (RNC) application controls packet communications through base stations serving wireless remote stations. In the embodiments, the RNC stores each packet received for a wireless remote station in a buffer and maintains a BCN counter value representing the amount of buffered data. The RNC maintains a maximum accumulation timer (Timeracc), and it restarts an inter-packet arrival timer (Timerint) upon receipt of each packet for the station. The RNC initiates transmissions to the station in response to certain events, including expiration of either of the timers Timerint and Timeracc, and if the BCN counter value exceeds a threshold. However, the transmissions use either a dedicated channel cell-state or a forward access channel state, depending on which event triggered each transmission. The RNC also may instruct the remote station to return to the forward access channel state following communication in the dedicated channel cell-state.Type: ApplicationFiled: August 1, 2006Publication date: November 30, 2006Applicant: Golden Bridge Technology, Inc.Inventor: Emmanuel Kanterakis
