    摘要: Disclosed is a system and method for channel decoding speech frames in a receiver capable of multiple (M) codec modes, wherein channel encoded speech frames include an inband bit portion and a speech portion. An inband bit decoder decodes the inband bit portion (700) of a received frame to obtain confidence levels associated with each of the M codec modes. Using these confidence levels, the codec modes are ordered from most to least likely. The speech frame is then decoded by a channel decoder using the most likely codec mode (704). A frame determination check (720) is performed to determine the quality of the decoded speech frame. If the decoded speech frame is determined to be of poor quality, then the channel decoding process is repeated using the next most likely codec mode (736) corresponding to the next highest inband bit decoding confidence level. This process is repeated until a good speech frame is decoded or some exit criteria is reached.

    摘要: A base station monitors the uplink load and sends control signals to one or more mobile terminals to selectively enable and disable compressed mode operation. The base station can divide the mobile terminals into groups and can assign different compressed mode patterns to different groups of mobile terminals so that the transmissions from mobile terminals in different groups while in compressed mode are not synchronized. If load imbalances occur, the network can reassign mobile terminals from one group to another.

    摘要: A femtocell base station is configured to transmit site-specific services data to in-range wireless devices, using a common broadcast channel. The site-specific services data identifies available services including, but not limited to, alternate radio signals available in the vicinity, such as FM radio signals, wireless local-area network (WLAN) signals, and the like; location-related services, including the availability of location beacon signals and/or location assistance data for use in position determination using assisted-GPS technology; and physical resources available to the device user, such as printers, copy machines, vending services, and the like. An exemplary mobile station is configured to extract site-specific services data from the femtocell base station signal, and to access a second radio signal using the site-specific services data. In some embodiments, the second radio signal may comprise a low-power FM radio signal, a wireless local-area network (WLAN) signal, a location beacon, or a radio-navigation signal.

    摘要: Light sources are affixed at appropriate positions in a multilevel structure or in an obstructed environment. The light sources generate modulated light signals, such as controlled light-emitting diodes, which identify the positions of the light sources by their three-dimensional global positioning coordinates and/or equivalent representation that specifies their in situ locations in the environment. Mobile communication devices, upon receiving the light signals, can derive spatial positioning information and transmit such information to a remote location, such as an emergency response system.

    摘要: Received signal quality (bit error rate) estimates for a communication channel are provided by a receiver apparatus which is connected to the communication channel and which includes a convolutional decoder providing an estimate of a transmitted data frame and an associated final decision metric. The bit error rate estimate is generated by a bit error rate estimation circuit which includes a memory containing values for mapping the final decision metric to a corresponding bit error rate estimate. The bit error rate estimate may be provided to a control node of the communication channel which may use the provided estimate to take a corrective action such as determining whether a handover to a different communication channel should be initiated based upon the bit error rate. The communication channel may be an allocated channel of a cellular radio communication network servicing a mobile terminal receiver apparatus with the control nodes being the base stations of the cellular network. The convolutional decoder may be a Viterbi decoder.

    摘要: An electronic device such as a cellular telephone, for example, includes a receiver that receives broadcast radio signals transmitted by a commercial broadcast radio station. The broadcast radio signals include information that identifies a location of the radio station, an antenna associated with the radio station, or the radio station. The device also includes positioning circuitry to allow the device to determine its current location. A controller in the device extracts the information identifying the radio station from the received broadcast signal, and acquires one or more satellites of a navigational system based on the information.
