    摘要: A method of operating a time division duplex based wireless communications system comprising the steps of establishing, at a base station, a Radio Resource Mapping Function (RMMF); deriving from the RMMF, from both the mean and standard deviation of the received signal to interference ratio (SIR) for all users, and from estimates of channel load conditions and interference levels, a Resource Metric Region (RMR) showing the number of users experiencing acceptable quality of service; and deciding, on the basis of the RMR, whether to admit a newly arriving call.

    摘要: Disclosed is a hybrid wireless communication system and a communication method in the system. The system supports time and frequency division duplexing modes and includes a base station having a cellular communication range based on a cellular mode and mobile stations within the cellular communication range. The base station divides each available frequency resource into frames for communication, and each frame switches between a real-time service mode and a non-real-time service mode at a switching time within the frame. Communication is performed with the mobile stations within the cellular communication range via at least one of an uplink and a downlink in the real-time service mode of each frame according to the frequency division duplexing mode. Communication is performed with the mobile stations via the uplink and the downlink in the non-real-time service mode of each frame according to an ad hoc mode based on the time division duplexing mode.

    摘要: A method of assessing a communication route comprising a plurality of links between nodes in a mobile ad-hoc network comprises calculating the two-hop residual bandwidth of each node I of the route as B I ⁡ ( t ) = B - ∑ J ∈ N ⁡ ( I ) ⁢ B ⁡ ( J ) ϕ where B is the raw channel bandwidth, the summation is the overall consumed bandwidth from node I's two-hop neighborhood nodes, JεN(I) and φ is a factor to account for protocol overhead, which may include handshaking, packet collision, re-transmission and/or back-off scheme traffic. An estimated transmission time for each of a plurality of links between said nodes may be calculated taking said two-hop residual bandwidth into account. For each possible route, a route efficiency function is determined at least by summing the estimated transmission times for all the links in the route, and the route in which the value of the route efficiency function is smallest is selected.

      摘要: In an embodiment, an apparatus may include a light source, a beam manipulator, an optical component, an analyzer, and a detector. The light source may generate an incident light at a first frequency. The beam manipulator may include one or more polyhedron-shaped prisms that may deflect the incident light for focus at a plurality of points on a sample. The optical component may collect the deflected incident light, focus the collected deflected incident light at the plurality of points on the sample, and collect scattered light from the sample. The scattered light may include elastic scattered light and/or inelastic scattered light. The inelastic scattered light may have a second frequency that is shifted up or down from the first frequency. The detector may detect the inelastic scattered light and the analyzer may identify a substance contained in the sample based on the detected inelastic scattered light.
