Abstract: A method for enhancing the fairness and performance in a multihop ad hoc network, the method usually including providing contention synchronization information regarding a transmission between nodes of the network, wherein the information is routinely provided to nodes in a range of two hops from the nodes participating at the transmission. The method also typically includes setting, after successfully finishing the transmission, a waiting time for the nodes participating at the transmission, in which these nodes backoff from accessing a transmission medium.

Abstract: A satellite radio receiver includes a display that displays information regarding one or more channels that are not currently being listened to. For a music channel, this information may include the name of the artist, the song title, time left in the song, etc. For a news channel, this information may include the news currently being discussed, the name of the news program, the time remaining, etc. For a sports channel, this information may include the name of the channel, a description of the sporting event, the time remaining, etc. The preferred embodiments include different ways to select which channels are “favorites” and therefore displayed on the display. One way is to select one or more channels that are assigned to preset buttons on the radio receiver. Another way is to keep track of which channels are most frequently listened to, and to display information regarding those channels.

Abstract: System and method for the adaptive control of VHF communications in aircraft. In one embodiment, the invention includes an adaptive communications system for an aircraft having a communications processor that accesses a communications switching model to select a preferred ground communications station. In another embodiment, a method of communication between an aircraft and a ground station includes receiving a communications switching model and determining a flight parameter for the aircraft as the aircraft navigates along a flight route and selecting a ground station based upon the determined flight parameter. The aircraft then communicates with the selected ground station. In still another embodiment, a method for compiling a communications switching model includes receiving signals from a ground station and measuring a signal strength. A preferred ground station is selected based upon the measured signal strength value.

Abstract: In a CDMA receiver, the TFCI decoding error is reduced. When the difference between TFCI correlation values is small and hence TFCI candidates are less credible, data is decoded using transport format information according to a plurality of TFCI having a high TFCI correlation value to select an appropriate TFCI using to a CRC judge result. Data is decoded according to the appropriate TFCI and is sent to the higher layer. Therefore, data decoded according to correct transfer format information can be reported to the upper layer. This resultantly keeps high utilization efficiency of finite wireless resources.

The method comprises detecting connection of an external device to a mobile communication terminal based on a signal generated by a first operation module of the mobile communication terminal; activating a connection interrupt routine, in response to the signal generated by the first operation module; controlling an active status of a second operation module by way of the first operation module to switch system operations from a first clock speed to a second clock speed; and establishing a signal transfer path between the mobile communication terminal and the external device.

Abstract: A system and method is shown for determining the spatial boundary of certain measurable phenomena, such as broadcast signals, at various locations within geographical areas covered by the phenomenon. Data representing relative signal quality at various locations within the geographical area is created within a mobile device, such as a cell phone capable of receiving the phenomenon. The data is stored and refined within the device so as to define weak signal quality areas within at least a portion of the geographical area traveled by the mobile device. The refinement, which in one embodiment comprises coalescing and splitting stored data locations in the device allows for long storage periods by reducing memory requirements. By devoting the majority of memory to locations in the vicinity of the good/bad boundary, the most detailed picture possible of the boundary is achieved for a given amount of memory.

Abstract: A limited acknowledgement-based communication methodology increases the throughput efficiency of a relay-based, extended range, wireless packetized data transmissions to a data-reception site from a data-sourcing site, geographically remote with respect to the data-reception site. Rather than return an acknowledgement for each received packet, the data-reception site returns an acknowledgement only after receipt of a group of packets. When returning an acknowledgement, the data-reception site identifies which packets of the group were not successfully received. Missing packets may be retransmitted by the data-sourcing transmitter either immediately, or in response to a subsequent poll.
