    摘要： A method of constructing a micro- or pico-cells and a virtual macro-cell hierarchical cellular system structure comprising contiguous cells each containing a base station and sectors, wherein a virtual cell comprising three surrounding FDD macro-cell base stations over underlay the TDD micro- or pico-cells. In the proposed TDD/virtual FDD hierarchical cellular structure, a method of locating underlay cells' base station and macro-cells' base station to keep a least interference distance and a method of aligning the TDD micro-or pico-cells' sectors antenna beam direction with the FDD macro-cells' sectors beam direction are proposed, such that this system can suppress the additional inter-system interference and adjacent channel interference. The algorithm of utilising and borrowing the underused FDD macro-cells' resource and the mechanism of deciding the feasible resource borrowing region and smart antenna applicable region is proposed in such a way that the radio network controller and TDD micro- or pico-cell base stations can build up and decide the preference list of which sector, users, and resource to be served, which eventually resulting in the flexible and adaptive radio resource management of the RNC and achieving the optimal utilisation of the overall system resource.

    摘要： Disclosed is a multicarrier-based wireless communication system including a base station for providing a multiple access service to terminals which filter multitone transmitting signals through filters and transmit the filtered signals. A transmitter of the respective terminals includes a multiplexer for multiplexing an input signal and outputting the signal as a plurality of transmitting signals, at least one filter bank for filtering the plurality of transmitting signals, an inverse fast Fourier transformer for executing inverse fast Fourier transform of the filtered transmitting signals output from the filter bank, and a filter information generator for providing filter information to the filter bank. Since the transmitter of the present invention distinguishes users from each other by a filter and thus no synchronization is required between users, which causes a problem in an uplink of the multicarrier-based wireless communication system, system performance can be expected to be improved.

    摘要： A velocity estimation apparatus and method for a communication system including a transmitter for transmitting signals through wireless channels and a receiver for receiving the signals and restoring data. The apparatus includes a pilot signal detector for detecting a pilot signal from a received signal, a maximum Doppler frequency estimator for estimating a maximum Doppler frequency using the pilot signal detected by the pilot signal detector, and an adaptive type band-limit filter having a limit band based on a previous output value of the maximum Doppler frequency estimator. By using the pilot signal, which is removed with noise, while passing through the band-limit filter, it is possible to precisely estimate a maximum Doppler frequency, and thereby estimate the velocity.
