    Abstract: 실시예들에서, 무선 수신기는 펌웨어에 의해 제어되는 하드웨어-기반 고속 푸리에 변환(FFT) 엔진을 사용한다. FFT 엔진은 작업 목록에 저장된 작업들을 실행시킨다. 각각의 작업은 신호의 상이한 일부분, 예컨대 하나 이상의 직교 주파수 분할 변조(OFDM) 심볼들과 연관된다. 각각의 작업은, 상기 엔진이 상기 신호의 상기 연관된 일부분, 상기 일부분에 대한 포인터, 그리고 출력을 저장하기 위한 메모리에 대한 다른 포인터를 프로세싱하도록 구성하기 위해 FFT 엔진을 위한 구성 정보를 포함할 수 있다. 상기 작업 목록은 펌웨어 제어될 수 있다. 작업 목록으로부터 작업들을 판독하여 실행시키기 위해 펌웨어에 의해 구동되는 구성가능한 하드웨어 파트로 상기 FFT를 분할하는 것은 FFT 프로세스의 속도를 높일 수 있고, 더욱 유연성 있게 한다. 서브-캐리어들을 그들의 에너지들에 따라 정렬하기 위한 하드웨어 비콘 정렬기가 상기 FFT 엔진에 커플링될 수 있다.

    Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatuses for decoding code words received over a MIMO channel.SOLUTION: A cost function is computed for each constellation point of an Mth rank or spatial layer, and Nof those constellation points having minimum cost are preserved as candidate points, where Nis a parameter specified to the decoding algorithm. In addition, a cost function may be computed for all possible transitions from the Ncandidate points of the Mth rank to all possible constellation points of the (M-1)th spatial layer, and Aof those transitions having minimum cost are preserved as candidate points. The process is repeated for all spatial layers, resulting in the identification of Ncandidate code words and their associated cost functions.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of efficiently sending signals on a configurable CDMA control segment.SOLUTION: To send signals, transmission parameters for the CDMA control segment 300 for a serving sector are determined. The enabled CDMA signaling channels for a terminal and the average transmission interval for each enabled CDMA signaling channel are determined. For each frame in which the CDMA control segment 300 is sent, the signaling channels to be sent on the CDMA control segment 300 in that frame are determined. The signals for each signaling channel are processed (e.g., encoded, channelized, scaled, and scrambled). The processed signals for all signaling channels are combined and mapped to a time-frequency region used for the CDMA control segment 300 in the frame.
