摘要： A signal reception apparatus and method for communication systems. The signal reception apparatus for communication systems according to the present invention is applicable to communication environments in which a plurality of sub-bands having different frequency bands are sequentially used for communications. An embodiment of the invention has a multi-band index generation unit, a multi-band frequency generation unit, a multiplication unit, a correlation signal reception unit, and a buffer unit. The multi-band index generation unit generates a multi-band index corresponding to a sub-band to which a received signal is transmitted in correspondence with the multi-band index. The multiplication unit outputs a signal obtained by multiplying the received signal by the multi-band frequency. The correlation signal reception unit integrates and outputs the signal of the multiplication unit based on an integral time set in correspondence with the multi-band index. Further, the buffer unit buffers the signal of the correlation signal reception unit to be outputted at a predetermined data rate.

摘要： A method and apparatus for adaptively determining weights for transmission antennas according to channel gains in a closed-loop transmit diversity system using a plurality of transmission antennas. The antenna weights are determined using channel characteristics which varies according to time and space, to thereby improve bit error rate performance. Parameters for fixing average transmission power per symbol according to the statistical channel characteristics for symbol energy and additive white Gaussian noise energy are previously determined to estimate channel characteristics. The antenna weights are determined using the parameters and channel gains estimated upon reception of data symbols.

摘要： Provided is a scheduling apparatus and method for allocating resources to individual users in a multiantenna system. An upper layer determines resources to allocate to respective users one a long term, and provides the ratio to a scheduler. Then the scheduler determines coefficients appropriate for the provided ratio. On the assumption that a statistical channel characteristic for a user is constant for a predetermined time, the scheduler determines a channel capacity average and a standard deviation for the user. The scheduler schedules resource allocation for individual users according to the channel capacity average and standard deviation values, which are the statistical characteristic values, and instantaneous channel capacity fed back for the individual users, together with the found coefficients.

摘要： A method for generating a parity check matrix of a Low Density Parity Check (LDPC) code. A base matrix is generated in which elements with a value of 1 are arranged at predefined distances. The elements with the value of 1 in the base matrix are replaced with predefined sub-matrices. The method can improve the performance of the LDPC code by implementing the parity check matrix in which the number of 4-cycles or 6-cycles adversely affecting the LDPC code performance is minimized.
