We propose a method of designing equiripple linear-phase FIR filters with linear constraint by carrying out the Remèz exchange algorithm. A novel technique is derived to convert a linearly constrained problem into an equivalent unconstrained one. We proposed a technique to modify the original desired frequency response so that the original linear constraint can be reduced to a simpler one (the ...

This paper describes recent experiences with evaluating and implementing advanced communication protocols on top of ATM. First, experiences and performance results with conventional TCP/IP over ATM based on Digital Equipment’s Gigaswitch/ATM are reported. Moreover, the behaviour and performance of application-level remote procedure call protocols with mass data transfer extensions over ATM is d...

This contribution focuses on the cost-effective management of the combined use of two procurement options: the short-term option is given by a spot market with random price, whereas the long-term alternative is characterized by a multi period capacity reservation contract with fixed purchase price and reservation level. A reservation cost, proportional with the reservation level, has to be paid...

One of the requirements for seamless mobility is efficient resource reservation and context transfer procedures during handoff. If context transfer and resource reservation can occur prior to handoff continuation of the same level of service as at the previous connection point is possible. Resource reservation is required to be nonaggressive for optimal use of limited bandwidth and a low call-b...

In this paper, a mathematical model for an extended multi-objective portfolio selection (EMOPS) problem is explored with liquidity considered as another objective function besides the risk and return. The mathematically formulated in uncertain environment. concerned uncertainty dealt by employing fuzzy numbers matrix While EMOPS converted into corresponding deterministic case based on α—level s...

Effective and efficient Quality of Service (QoS) management is critical for a service grid to meet the requirements of both grid users and service providers. We introduce Q-GSM, a scalable framework for service management in grid environments, to address this problem. Main characteristics of our framework are 1) grid level resource reservation mechanism; 2) mapping application level service qua...

In this paper, we study robust resource allocation for the multi-user full-duplex (FD) multiple-input multiple-output (MIMO) communication systems. Particularly, we aim at minimizing uplink (UL) transmit power and downlink (DL) transmit power simultaneously while guaranteeing the quality of service (QoS) requirements regarding secure UL and DL communication, under the consideration of the imper...
