Patent number: 8688124Abstract: Provided are methods and systems of managing a handoff in a multimedia communication network. Embodiments include estimating the voice quality of a communication route in the network. The voice quality may be estimated by using a total voice quality metric involving subtracting various impairments to the voice signal. Impairments may result from the type of vocoder in a communication route, the error or loss associated with RF links and network links, and delays in the communication route. After subtracting the impairments to obtain the total voice quality metric for the communication route, the total voice quality metric may be compared with a threshold and/or other total voice quality metrics of other communication routes to determine whether and when a handoff should be made.Type: GrantFiled: November 5, 2012Date of Patent: April 1, 2014Assignee: General Electric CompanyInventors: Richard Louis Zinser, Michael James Hartman, John Erik Hershey

Patent number: 8521520Abstract: Provided are methods and systems of managing handoffs in a wireless communication system having different types of vocoders. Some embodiments include translating state memory of a first vocoder to a second vocoder using a state memory transcoder. The state memory may be delayed to align differences in algorithmic delays between the first vocoder and the second vocoder. In one embodiment, a speech signal may be decoded from the first vocoder, delayed, and encoded to the second vocoder. Furthermore, for a period of time during and/or adjacent to the handoff, the first vocoder may output with decreasing amplitude while the second vocoder outputs with increasing amplitude. Such techniques may be used alone or in combination.Type: GrantFiled: February 3, 2010Date of Patent: August 27, 2013Assignee: General Electric CompanyInventors: Richard Louis Zinser, Michael James Hartman, John Erik Hershey

Publication number: 20130101116Abstract: Provided are methods and systems of using division-free duplexing (DFD) in a cable communication network. Techniques for applying DFD in a cable communication network may enable data to be transmitted and received over a coaxial cable without using division duplexing techniques. For example, the cable communication network may include DFD enabled network nodes and each subscriber to the cable network may be equipped with a DFD system configured to operate in a DFD mode. In some embodiments, oppositely propagating signals may be transmitted over one frequency channel, and DFD techniques may be used to recover originally transmitted signals. Further, in some embodiments, DFD techniques may be used with encryption methods to increase the security of data transmitted in the cable communication network.Type: ApplicationFiled: October 19, 2011Publication date: April 25, 2013Applicant: General Electric CompanyInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser

Patent number: 8379584Abstract: Provided are methods and systems of using division-free duplexing (DFD) to reduce rendezvous time between two or more cognitive radio devices. The cognitive radio devices may opportunistically use available frequency spectra by communicating over available channels. To communicate, a first device may rendezvous with a second device by transmitting a beaconing signal over a frequency on which the second device is listening. DFD techniques may enable each of the devices to listen to a channel while concurrently transmitting beacon signals over the same channel. As periods of listening and periods of transmitting over the same channel need not be separated due to the transmitter cancelling approach used in DFD techniques, rendezvous time may be significantly reduced. Further, embodiments include a generalized DFD (GDFD) approach wherein devices listen to a broad band of frequencies, thus further reducing rendezvous time.Type: GrantFiled: April 15, 2010Date of Patent: February 19, 2013Assignee: General Electric CompanyInventors: Michael James Hartman, John Erik Hershey, Richard Louis Zinser, John Anderson Fergus Ross, Michael J.

Publication number: 20120307617Abstract: Techniques are provided for increasing spectral efficiency over data channels in a storage or communication system. In some embodiments, data may be encoded and transmitted over multiple channels. The transmitted data from the multiple channels may be considered together as a channel bundle, thereby increasing the edge transitions of the group of signals to improve clock recovery and reduce coding constraints. In some embodiments, the channel bit size is reduced to maximize data rates based on the reduced coding constraints. Furthermore, the channel bundle has only one channel with timing markers, so that a receiver may receive information from the channel bundle and recover clocking based on the timing markers in the one channel.Type: ApplicationFiled: June 6, 2011Publication date: December 6, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser, Xiaolei Shi

Publication number: 20110249596Abstract: Provided are methods and systems of using division-free duplexing (DFD) in a communication network. Techniques for applying DFD in a communication network may decrease bottlenecks in the network by allowing one or more network nodes to transmit and on substantially the same frequency and at substantially the same time. In one embodiment, one or more nodes in the network may be DFD enabled, and may be configured to operate in either a conventional mode or a DFD mode. The mode of operation of DFD enabled nodes may depend on the quality of signals transmitted to and/or received at the DFD enabled nodes. Further, the mode of operation may change dynamically, and may be substantially controlled by any suitable processor in the network.Type: ApplicationFiled: April 9, 2010Publication date: October 13, 2011Applicant: GENERAL ELECTRIC COMPANYInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser
