摘要： Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. The present system used point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements can be co-located with or replace the standard network elements. A tree-and-branch network architecture is therefore established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth.

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 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 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： 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： 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.

摘要： In an ad-hoc mobile network, a geometry-based routing algorithm (GRA) is used to route traffic from a source node to a destination node. In the GRA, a source node maintains location information and routing information for all nodes in a local area and approximate location information for at least some nodes outside the local area. If the source node has to send a packet to a destination node outside their local area, then the source node uses the approximate location information of the destination node to identify which node in its local area is closer to the destination node than the source node. The source node then sends the packet to the identified local node for further routing.
