    Existing narrowband jammer suppressors for DS-CDMA, typically function independently of the multiuser interference cancellation strategy used. Besides, certain high-performance jammer suppression techniques, e.g., linear MMSE suppression, assume that the powers and frequencies of the interfering signals are known, or that they can be adaptively estimated. The former is never true in practice and t... View full abstract»

    To achieve good predictability of multimedia service behaviour in cell/packet based networks, end-to-end quality of service (QoS) guarantees must be supported. In military networks, when not enough capacity is available to support all traffic requests, messages carrying mission critical information should have higher priority over less important ones. In addition, it is preferable to gracefully &l... View full abstract»
