摘要： A universal mobile telecommunications system (UMTS) receiver uses Pilot Symbol Assisted Modulation (PSAM) in demodulating a received Binary Phase Shift Keying (BPSK) signal. The UMTS receiver uses a ratio of the transmitted energy per pilot symbol to the transmitted energy per data symbol as an index into a look-up table to return a value for a scale factor for use in demodulation of the received signal, which provides better performance during periods when the fading distribution is unknown.

摘要： In an ad-hoc mobile network, a geometry-based routing protocol (GRP) is used to route traffic from a source node to a destination node. In the GRP, each node maintains a location list, which comprises location information for a number of nodes of the ad-hoc mobile network. Periodically, each node transmits to its direct neighbors (i.e., those nodes with which it has a point-to-point link) (a) its location, and (b) its location list. Each node that receives a location list from an adjacent node merges the received location list into its own location list such that location information for existing nodes, and/or newly identified nodes, is current.

摘要： A UNMTS (universal mobile telecommunications system) based system comprises a common control point, a number of base stations, K, and a mobile terminal. During a soft handoff involving the K base stations and the mobile terminal, the common control point receives individual user channel transmit powers from each of the K base stations. In addition, the common control point receives two parameters from the mobile terminal—the identity of that base station involved in the soft handoff that has the strongest received signal at the mobile terminal and, on an average, a value representing how much stronger the received SNR was in comparison to the SNR target maintained by the mobile terminal. The common control point then decides on a downlink reference user channel transmit power for each of the base stations as a function of the individual user channel transmit powers reported by each base station involved in the soft handoff and the information provided from the mobile terminal.

摘要： In a wireless communications system, a base station employs a bit error rate (BER) based Reverse Outer Loop Power Control (ROLPC) technique. The ROLPC technique uses either instantaneous or weakly filtered values of the BER for comparison with a BER target value for adjusting a target signal-to-noise ratio (SNR). The BER target value is varied as a function of a second order statistic (e.g. variance, standard deviation) of the received SNR. In another embodiment, a symbol error count based ROLPC technique uses adaptive SER targets. In particular, a base station uses a 2nd order statistic, e.g., standard deviation (variance), to identify, or act as a signature of, a particular cellular (wireless) communications environment. The base station monitors the standard deviation of the symbol error count of a received signal (transmitted from a mobile station). The target signal-to-noise ratio ((Eb/N0)T) of this received signal is adjusted as a function of the value of the standard deviation and the adjusted (Eb/N0)T target is used to provide power control.

摘要： In a UMTS (universal mobile telecommunications system) based system, a wireless receiver implements “effective signal-to-noise (Eb/No) based BER estimation.” In particular, the wireless receiver comprises a rake receiver, a processor and memory. The rake receiver processes a received signal and provides signal-to-noise ratio values for each slot of each received frame of the received signal. The processor converts these signal-to-noise ratio values for each received frame into an effective signal-to-noise ratio value for the received signal. The processor then uses the effective signal-to-noise ratio value as a pointer, or index, into a look-up table (stored in the memory) and retrieves a BER estimate therefrom.

摘要： A novel topology sensing methodology is provided for point-to-point link setup among a set of network nodes, which are mobile. The technique provided is TDMA contention-based, where each network node sends pilot signals to announce its existence. Pilot signals transmitted by network nodes are used by surrounding nodes to extract various pieces of information such as node identity, node location and potential link quality. Information collected from pilot signals of neighboring nodes is used in conjunction with other topological criteria to identify the best set of nodes with which a given node should establish links. The topology sensing methodology avoids duplexer problems and attempts to achieve minimum collision by allowing the nodes to continually monitor available pilots and transmit on the least-interference channels. The topology sensing methodology can also optionally make use of GPS information, when available, in order to provide an accurate map for communicating nodes and improve the link setup process.

摘要： In a UMTS (universal mobile telecommunications system) based system, a wireless receiver comprises a convolutional decoder, a processor and memory. The convolutional decoder processes a received signal and provides a Yamamoto-Itoh (YI) metric to the processor. The processor (a) retrieves, from a look-up table stored in the memory, a compensation factor as a function of the YI metric value provided by the Viterbi decoder; (b) retrieves, from another look-up table stored in the memory, an initial BER estimate as a function of the YI metric; and (c) modifies the initial BER estimate with the retrieved compensation value to provide a BER estimate.
