Patent number: 8077780Abstract: An improvement to multi-carrier communication, such as an OFDM and MC-CDMA system, where in a multipath or phase distorted channel, the received signal is flat with respect to frequency and linear with respect to phase. A first unit transmits a plurality of multi-carrier signals, which include unmodulated carrier signals. A second unit receives the plurality of multi-carrier signals, and determines the in-phase and quadrature amplitudes or powers of the unmodulated carrier signals of the received multi-carrier signal. The second unit compares the measured in-phase and quadrature amplitudes or powers of the unmodulated carrier signals to predetermined criteria, and generates adjusting data from the compared in-phase and quadrature amplitudes or powers. The first unit uses the adjusting data to pre-distort the next plurality of multi-carrier signals to be transmitted, the in-phase and quadrature amplitudes or powers of the plurality of multi-carrier signals.Type: GrantFiled: April 17, 2006Date of Patent: December 13, 2011Assignee: Linex Technologies, Inc.Inventors: Donald L.

Patent number: 8072921Abstract: System and method for reducing acquisition time of packets in a FDD system, such as a spread-spectrum or OFDM system. A remote unit transmits a multi-tone packet. The multi-tone packet has a plurality of tones with each tone having a different power level, and at a different frequency, from other tones in the plurality of tones. The base station receives the multi-tone packet. The base station compares the plurality of tones from the received multi-tone packet to a threshold or other selection criteria. A tone is selected from the plurality of tones meeting desired selection criteria. Based on the selected tone, the base station transmits a BS packet with the BS packet having power information from the power level of the selected tone.Type: GrantFiled: February 13, 2006Date of Patent: December 6, 2011Assignee: Linex Technologies, Inc.Inventors: Donald L.

Patent number: 7876709Abstract: A mesh network communication system including one or more mesh networks and a plurality of remote subscriber users employing wireless, spread spectrum type communications for communicating with an access node in one of the mesh networks. The remote subscriber units can be mobile and can use handover to change nodes within a mesh network without a disruption of communication. The system and methods determine the location of a remote subscriber unit in a mesh network by the remote subscriber unit providing the access node with its home address and ID such that if the access node is not the home node, the home node is notified of the visiting node address such that the home node always knows the location of any remote subscriber unit based at the home node. Accordingly, communication between remote subscriber units where one of the remote subscriber units is not currently located at its home node can be accomplished without using the home node.Type: GrantFiled: October 5, 2007Date of Patent: January 25, 2011Inventors: Donald L.

Patent number: 7613247Abstract: A communications system and method having a transmitted data rate determined by an error rate syndrome at a receiver. Data are demultiplexed into a plurality of data channels, and processed as a plurality of channels. A combiner combines the plurality of channels as a multiplexed signal. At a receiver, the multiplexed signal is despread into a plurality of despread channels. A syndrome signal is generated from an error rate of the channels. From the syndrome signal, a desired-data rate is determined for the transmitter.Type: GrantFiled: April 25, 2005Date of Patent: November 3, 2009Assignee: Linex Technologies, Inc.Inventor: Joseph Garodnick

Publication number: 20080242367Abstract: A spread spectrum base station comprises an automatic gain control (AGC) circuit having an input configured to receive a received spread spectrum signal and gain control the received spread spectrum signal to produce a gain controlled signal. A correlation circuit has an input configured to receive the gain controlled signal and correlate the gain controlled signal with a code to produce a despread signal. A power measurement and comparator circuit is configured to receive the despread signal and a control level of the AGC circuit. The circuit processes at least the despread signal and the control level to produce a processed signal and compares the processed signal with a threshold to produce a comparison signal. The comparison signal is used to produce a power command. A multiplexer multiplexes the power command with a signal for transmission over an antenna.Type: ApplicationFiled: June 9, 2008Publication date: October 2, 2008Applicant: INTERDIGITAL TECHNOLOGY CORPORATIONInventors: Donald L.

Patent number: 7187706Abstract: A spread-spectrum, code-division-multiple-access (CDMA), system with a remote station (RS) communicating with a first base station (BS). The remote station receives the first BS-packet signal, and transmits a first RS-packet signal to the first base station. The first RS-packet signal is spread by a first RS-chip-sequence signal at a second frequency. The first base station receives the first RS-packet signal. The first base station stores and forwards the despread first RS-packet signal to a central office (CO). The remote station monitors control and packet transmission channels of other base stations in geographic proximity to the remote station. Each of the base stations transmit BS-packet signals. The remote station determines, based on signal metrics and available capacity, when to change from the first base station to the second base station. The second base station stores and then forwards the despread second RS-packet signal to the central office.Type: GrantFiled: October 2, 2001Date of Patent: March 6, 2007Assignee: Linex Technologies, Inc.Inventors: Donald L.

Patent number: 7167503Abstract: A distributed spread-spectrum network, comprising remote stations and nodes. One or more hub node(s) connect(s) to a central telephone office. A node's spread-spectrum transceiver communicates, using packets having spread-spectrum modulation, over radio waves, with the remote stations. Each packet has a source address and a destination address, and may have other information such as a header, start of message, end of message, flow-control information, forward error correction, and message data. A store-and-forward subsystem stores and forwards one or more packets to and from the remote station. The store-and-forward subsystem stores and forwards the one or more packets to and from another node. A flow-control subsystem controls the store-and-forward subsystem, to store each packet arriving at the spread-spectrum transceiver. The flow-control subsystem communicates traffic information between each of the nodes.Type: GrantFiled: November 18, 2002Date of Patent: January 23, 2007Assignee: Linex Technologies, Inc.Inventors: Donald L.
