  • This paper deals with enhancing the error resilient of the Switched Split Vector Quantization (SSVQ) techniques by adopting the optimal Index Assignment approach, a Joint Source-Channel coding method. SSVQ is one of the latest structured vector quantization schemes and it has several advantages over other schemes.

  • In the present paper we give the definition of the graph radio coloring concept which is a graph coloring generalization. We also introduce radio coloring invariants which are of a great practical importance to problems regarding the allocation of diverse frequencies in order to avoid interference occurrences between channel transmissions.

  • The Satellite Switched CDMA Throughput Overview As we have discussed in Chapters 3 and 4, the satellite switched CDMA system provides on-board switching which operates with demand assignment control. This approach resolves both the multiple access and switching problems while it allows efficient utilization of the system resources. This is achieved with Traffic channel assignment algorithms which can maximize throughput and integrate the traffic of circuit calls and data packets.

  • Channel Assignment Problems (CAPs) occur in the design of cellular mobile telecommunication systems (Jordan, 1996; Katzela and Naghshineh, 1996; MacDonald, 1979); such systems typically divide the geographical region to be serviced into a set of cells, each containing a base station. The available radio frequency spectrum is divided into a set of disjoint channels; these must be assigned to the base stations to meet the expected demand of each cell and to avoid electromagnetic interference during calls....

  • The reader may have observed several times in the preceding sections that there was a close connection between sets and statements, and between set operations and compounding operations. In this section we shall formalize these relationships. If we have a number of statements relative to a set of logical pos- sibilities, there is a natural way of assigning a set to each statement. First of all, we take the set of logical possibilities as our universal set. Then to each statement we assign the subset of logical possibilities of the universal set for which that statement is true.

  • Scorpion toxins that affect sodium channel (NaCh) gating in excitable cells are divided into a-andb-classes. Whereas a-toxinshavebeen found inscorpions throughout theworld, anti-mammalianb-toxins have been assigned, thus far, to New World scorpions while anti-insect selective b-toxins (depressant and excitatory) have been described only in the Old World. 2 This distribution suggested that diversification ofb-toxins into distinct pharmacological groups occurred after the separation of the continents, 150 million years ago....

  • The Adaptive Security Algorithm (ASA), used by the PIX Firewall for stateful application inspection, ensures the secure use of applications and services. Some applications require special handling by the PIX Firewall application inspection function. Applications that require special application inspection functions are those that embed IP addressing information in the user data packet or open secondary channels on dynamically assigned ports.

  • The tremendous growth of the mobile users’ population coupled with the bandwidth requirements of new cellular services is in contrast to the limited spectrum resources that have been allocated for mobile communications. The objective of channel allocation is to assign a required number of channels to each cell such that efficient frequency spectrum utilization is provided and interference effects are minimized.

  • In a cellular network, there are ongoing requests for communication links from mobiles in each cell to the base stations responsible for the cell. In FDMA or TDMA networks, the available spectrum is divided into narrow frequency channels, and each communication request is served by the assignment of a frequency channel. Spectrum is a scarce resource, and careful assignment of channels to calls is critical to being able to maximize the number of users in the network.
