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 preprocessing apparatus and method for a transmitter and a receiver to prevent system performance degradation caused by Inter-Channel Interference (ICI) or inter-symbol interference (ISI) in an OFDM system. In the OFDM system using N carriers having different frequency bands and K carriers of the N carriers designated as redundant carriers, the transmitter renders ICI-causing parts to be zeroes in a data frame, when a cyclic prefix is not longer than a channel impulse response. Therefore, the ICI is prevented. The receiver eliminates the ISI involved in a current frame using an interference estimated from a previous data frame. Therefore, noise spread caused by the use of redundant carriers is prevented and system complexity is remarkably reduced.

摘要： The present invention relates to a slurry for use in metal chemical-mechanical polishing (CMP) and a preparation method thereof. More particularly, the invention relates to a slurry for use in metal CMP, in which iron ions or divalent or higher valent metal ions are physico-chemically adsorbed on colloidal silica particles in the form of particles by a reduction, hydrolysis, impregnation or precipitation method, as well as a preparation method thereof. The slurry useful for metal CMP prepared according to the present invention has a uniform particle size distribution, and shows increased efficiencies as an oxidation catalyst and polishing slurry chemically adsorbed with metal particles, as compared to the prior metal CMP slurry distributed with metal ions. Also, the inventive slurry has long-term storage stability, since it does not show coagulation and precipitation phenomena even after it is stored for more than one year without a dispersant or a dispersion stabilizer. Furthermore, the prior fumed silica contains a large amount of environment-harmful substances for distribution stabilization, such as surfactants and amine compounds, whereas the inventive colloidal silica contains no environment-harmful substances as described above, and thus, is eco-friendly.
