摘要： A method and apparatus for supporting a priority transmission of broadcasting data in a transmitter of a digital broadcasting system. A determination is made as to whether a priority transmission of one broadcasting service to be provided is supported. If the service supports the priority transmission, a plurality of subchannels to be transmitted for the service are set and a priority of the data to be mapped to the plurality of subchannels is set. The data of the broadcasting service is mapped to the plurality of subchannels according to the priority. Data streams mapped to the plurality of subchannels are encoded in different encoders and the encoded data streams are transmitted.

摘要： A beam-forming apparatus and method for improving system performance using a spatial interpolation and at least one Angle of Arrival (AoA) in a system based on regular spatial sampling is provided. The AoA is estimated using a carrier-to-interference ratio. Beam-forming angles are distributed and steered in a predefined scheme such that an identical process is applied in all directions. According to this steering, a linear system model is computed based on regular spatial sampling using regular spatial separation at beam angles. Beam-forming performance is improved by compensating for a difference between adaptive and sector-type arrays. Only the steps of computing a spatial interpolation and determining an angle range for beam-forming using at least one AoA are added. The precision of estimating an AoA and the precision of beam-forming increase without an additional antenna. Because the system is simpler than that of an adaptive beam-forming system, significant gain is obtained.
