| 31 | 7412020 | Training for time-selective wireless fading channels using cutoff rate | The optimal allocation of resources--power and bandwidth--between training and data transmissions is considered for time-selective Rayleigh flat-fading channels under the cutoff rate criterion. The transmitter, assumed to have statistical channel state information (CSI) in the form of the channel Doppler spectrum, embeds known pilots symbols into the transmission stream. At the receiver, instantaneous, though imperfect, CSI is acquired through minimum mean square estimation of the channel based on some subset of pilot observations. The cutoff rate is computed and the optimal resource allocation is developed using, for example, a Gauss-Markov correlation model of a communication channel or a Jakes model. | Saswat Misra (Potomac, MD), Ananthram Swami (Silver Spring, MD) | The United States of America As Represented By The Secretary of The Army (Washington, DC) | 2005-06-27 | 2008-08-12 | H04L23/00 | 11/166077 |

| 33 | 7289484 | Call-fail-safe method for wireless traffic distribution across bands | This invention presents an efficient and efficacious method for an equitable distribution of wireless traffic across the 800 and 1900 MHz bands. Even though traffic distribution across bands is desirable, there is a risk of call failure because of location of the mobile in the vicinity of a BTS group with low capacity in the other band. The method proposed here tells how decisions to migrate calls across bands can be made robust against call failures without imposing unreasonable constraints that make such decisions sparing. It presents: (i) a simple and effective quality measure for carrier-to-carrier comparison, (ii) convergence criteria flagging the convergence of the best carrier determination process for each BTS site using the afore mentioned quality measure, (iii) an effective procedure for their implementation, (iv) a decision procedure for selection of the band and carrier for call setup based on the best carriers of individual sites within the possible reach of the mobile in the two bands, and (v) an overall method that makes use of these components. It also presents method of extending this invention to next generation wireless systems that possibly operate in more than two frequency bands. | Parthasarathy Guturu (Richardson, TX), Abdennaceaur Lachtar (Richardson, TX) | Nortel Networks Limited (St. Laurent, Quebec, CA) | 2002-07-12 | 2007-10-30 | H04L12/56 | 10/194329 |
| 34 | 7271740 | System and process for providing improved aircraft operational safety | The present invention relates to a system and a process for providing improved operational safety for aircraft. The system/process of the instant invention utilizes real-time, two-way transmission of voice and/or text and flight-critical data between an aircraft and a ground-based computer workstation, where transmitted information monitored and acted upon as necessary by a qualified flight safety person, e.g., a appropriately trained individual (including but not limited to a safety pilot or other person trained in safety procedures) . This safety person can perform a number of functions that would enhance flight safety, such as reducing the workload of the primary pilot (s) , assisting in the performance of routine checklists, monitoring communications with air traffic control, and advising the pilot in the aircraft on how to handle any in-flight situations that may arise. By providing many if not all of the advantages of a second or third pilot in the aircraft cockpit without imposing additional weight or space requirements on the aircraft, the system/process of the instant invention can increase flight safety while reducing the associated costs. | Mark R.

| 45 | 6430168 | CDMA base station lantern application | In a hierarchical network system, at least one comparatively small underlay cell is embedded within a comparatively large overlay cell for the purpose of increasing the network capacity of certain area inside the overlay cell. The underlay cell is configured within an overlay cell to have both a traffic carrier and a pilot beacon, or a ''Lantern,'' carrier. The Lantern carrier, which comprises the Pilot, Paging and Sync channels, should be programmed to set its overhead power level to be lower than an overhead channel power level of the traffic carrier. Thus, the coverage or the footprint of the traffic carrier can always encompasses the footprint of the Lantern carrier. Hence, the quality of a traffic signal is always ensured when a mobile telecommunication unit (MU) is switched from the overlay cell to the underlay cell. When the MU is active, it will be switched to the underlay cell when it detects the Lantern carrier. When the MU is in an idle mode, a Global Service Redirection message in the Lantern carrier's paging channel directs the handoff to the traffic carrier. When the MU leaves the underlay cell, the wireless service is handed back to the overlay cell or other surrounding networks by going through steps directed by an Enhanced Hard Handoff (EHHO) protocol. | Roderick James Djurkovic (Allen, TX), Farhad Bassirat (Plano, TX) | Nortel Networks Limited (St. Laurent, CA) | 1999-10-18 | 2002-08-06 | H04Q7/38, H04B7/005, H04Q7/36, H04B007/00 | 09/420326 |
