Abstract:
넓은 간섭 신호 전력 레벨에서 높은 스루풋을 달성할 수 있도록 본 코드워드 및 간섭 코드워드를 동시에 복구할 수 있는 알고리즘을 저 복잡도로 구현할 수 있는 장치 및 방법이 제공된다. 디코딩 할 때 간섭 신호를 함께 고려하여 원하는 코드워드(desired codeword)와 간섭 코드워드를 동시에 복원함으로써 간섭 신호의 전력 레벨에 상관없이 높은 스루풋 성능을 달성할 수 있다.
Abstract:
A numerically-controlled oscillator capable of outputting a sine signal and a cosine signal, and an operating method thereof are provided to simply calculate a first address and a second address about an input signal phase value by using a function value calculated by a cosine function. An address generator(34) outputs a first address(Ac) about a function value of a cosine signal corresponding to a phase value of an input signal, a first code(Sc) about a code conversion of a function value of the cosine signal, a second address(As) about a function value of a sine signal, and a second code(Ss) about a code conversion of a function value of the sine signal. A look up table memory(32) outputs a first function value and a second function value corresponding to the first address and the second address by using a look up table. A code converter(36) outputs the cosine signal and the sine signal by converting codes of the first function value and the second function value according to a set reference.
Abstract:
A resource allocation apparatus in a cellular communication system including multiple cells determines a resource partitioning ratio of the current resource frame using traffic load on multiple cells measured during the previous resource frame and the marginal utility of each partitioned section, partitions the current resource frame into multiple partitioned sections according to the determined resource partitioning ratio, and allocates the multiple partitioned sections to users.
