Training Sequence Design for Discriminatory Channel Estimation in Wireless MIMO Systems

IEEE Transactions on Signal Processing, 2010

This paper proposes a training-based channel estimation scheme for achieving quality-of-service discrimination between legitimate and unauthorized receivers in wireless multiple-input multiple-output (MIMO) channels. The proposed method has applications ranging from user discrimination in wireless TV broadcast systems to the prevention of eavesdropping in secret communications. By considering a wireless MIMO system that consists of a multiple-antenna transmitter, a legitimate receiver ...

  • Training Sequence Design for Discriminatory Channel Estimation in Wireless MIMO Systems

    This paper proposes a training-based channel estimation scheme for achieving quality-of-service discrimination between legitimate and unauthorized receivers in wireless multiple-input multiple-output (MIMO) channels. The proposed method has applications ranging from user discrimination in wireless TV broadcast systems to the prevention of eavesdropping in secret communications. By considering a wireless MIMO system that consists of a multiple-antenna transmitter, a legitimate receiver (LR) and an unauthorized receiver (UR), we propose a multi-stage training-based discriminatory channel estimation (DCE) scheme that aims to optimize the channel estimation performance of the LR while limiting the channel estimation performance of the UR. The key idea is to exploit the channel estimate fed back from the LR at the beginning of each stage to enable the judicious use of artificial noise (AN) in the training signal. Specifically, with knowledge of the LR's channel, AN can be properly superimposed with the training data to degrade the UR's channel without causing strong interference on the LR. The channel estimation performance of the LR in earlier stages may not be satisfactory due to the inaccuracy of the channel estimate and constraints on the UR's estimation performance, but can improve rapidly in later stages as the quality of channel estimate improves. The training data power and AN power are optimally allocated by minimizing the normalized mean-square error (NMSE) of the LR subject to a lower limit constraint on the NMSE of the UR. The proposed DCE scheme is then extended to the case with multiple LRs and multiple URs. Simulation results are presented to demonstrate the effectiveness of the proposed DCE scheme.

  • An Absolute QoS Framework for Loss Guarantees in Optical Burst-Switched Networks

    <para> In order to meet the requirements of real-time applications, optical burst switched backbone networks need to provide quantitative edge-to-edge loss guarantees to traffic flows. For this purpose, there have been several proposals based on the relative differentiation quality of service (QoS) model. However, this model has an inherent difficulty in communicating information about internal network states to the edge in a timely manner for making admission control decisions. In this paper, we propose an absolute QoS framework to overcome this difficulty. The key idea is to offer quantitative loss guarantees at each hop using a differentiation mechanism and an admission control mechanism. The edge-to-edge loss requirement is then translated into a series of small per-node loss probabilities that are allocated to the intermediate core nodes. The framework includes a preemptive differentiation scheme, a node-based admission control scheme, and an edge-to-edge reservation scheme. The schemes are analyzed and evaluated through simulation. It is shown that the framework can effectively offer quantitative edge-to-edge loss guarantees under various traffic conditions. </para>

  • Quality‐of‐Service Routing

    Quality of service (QoS) is a parameter for standardizing the performance of a network in terms of the assurance and level of the services it offers. This chapter presents different sets of QoS parameters used by various organizations or in different literature sources in order to illustrate QoS measures. The International Engineering Task Force (IETF) has defined two models for implementation of QoS, differentiated services and integrated services. This chapter presents an overview of some of the QoS‐based path selection algorithms, such as the shortest widest path (SWP), and utilization‐based algorithms. In a QoS unicast routing, the data has to be sent from the source to only one destination through the feasible path that satisfies the QoS constraints. A QoS unicast routing protocol is broadly classified on the basis of the routing metrics into two categories: link‐constrained routing and link optimization routing. QoS multicast routing protocols are required to provide a path from a source to many destinations under constrained parameters as defined in the service level agreement (SLA).
