    ABSTRACT: This paper presents the performance evaluation of a TD-LTE/DTV heterogeneous system. Two coexisting scenarios are considered, DTV interfering with TD-LTE, and TD-LTE interfering with DTV. The TD-LTE uplink and downlink in both urban and rural environments are examined. Both the LTE capacity loss and DTV coverage loss are evaluated. Results are presented which indicate that the interference from DTV has a greater impact on the TD-LTE uplink than the downlink, and a DTV receiver is affected more seriously by the TD-LTE downlink.

    ABSTRACT: Fitting noisy measurements to a circle is a classic statistical estimation problem. In this paper, we make two contributions to the study of this problem. First, we propose a novel formulation of the maximum likelihood (ML) estimator for identifying the center and radius of the circle from noisy measurements. This new estimator uses the unknown true values of the measurement points as the nuisance parameter to obtain an exact ML formulation. We then examine the Karush-Kuhn-Tucker (KKT) conditions for the optimum solution to the ML estimator. We show analytically that this new estimator is in fact equivalent to the well-known least squares (LS) form of the circle fitting problem. Second, from the insights gained in deriving the optimum solution, a computationally simple circle fitting algorithm based on greedy search is proposed. Performance results are given to illustrate the performance of the proposed algorithm.

    ABSTRACT: In this paper, we propose a mode transfer architecture and cross layer design for connection aware applications in wireless communication systems. System architecture design and implementation are considered, and practical design examples are given based on existing wireless systems. To evaluate the proposed method, the performance of the network before and after mode transfer is compared. An unequal error protection (UEP) scheme for video frame transmission is also introduced to illustrate and evaluate the possible gain for video streaming with cross layer design.

    ABSTRACT: With the increasing convergence and cooperation among wireless networks, network awareness of user equipment (UE) has become very important. A practical solution for network information delivery for UE, Cognitive Pilot Channel (CPC), has recently been proposed. It can provide UE with the necessary network information for network selection by using the public signaling channel. In this paper, a cognitive multicast CPC scheme is proposed. It can greatly improve the on-demand CPC delivery efficiency, and also reduce the time delay of information delivery. The cognitive characteristics of the proposed multicast CPC scheme can easily be adapted to different heterogeneous network architectures.

    ABSTRACT: The success of cellular communications has resulted in large commercial mobile communication systems with billions of user. Many new technologies have been proposed to improve the performance and capacity of these systems. Among these, space-time coding (STC) is a technology, which can provide good performance through spatial diversity. Space-time block codes (STBC) have been incorporated in third generation (3G) cellular protocols. In this paper, we consider the implementation of a new cellular systems with transmit diversity first introduced in [W. Li and T.A. Guilliver, 2002].
