Abstract: A multiuser detector that detects and decodes synchronous or asynchronous CDMA subchannels having different spreading factors with reduced computational complexity. The multiuser detector is compatible with ZF-BLE, MMSE, decorrelating detectors and the like using Cholesky decomposition to minimize numeric operations. The system and method arranges the columns of system transmission response matrices representing the response characteristics of individual users into a total system transmission response matrix which represents a plurality of matched-filter responses for a given block of received data. The invention in conjunction with Cholesky decomposition reduces the number of required mathematic operations prior to parallel matched filtering.

Abstract translation: 一种多用户检测器，其检测并解码具有不同扩频因子的同步或异步CDMA子信道，降低了计算复杂度。 多用户检测器与使用Cholesky分解的ZF-BLE，MMSE，去相关检测器等兼容，以最小化数字运算。 系统和方法将表示各个用户的响应特性的系统传输响应矩阵的列排列成表示针对给定的接收数据块的多个匹配滤波器响应的总系统传输响应矩阵。 本发明结合Cholesky分解在并行匹配滤波之前减少了所需数学运算的数量。

Abstract: A multiuser detector method and receiver that detects and decodes synchronous or asynchronous CDMA subchannels having different spreading factors with reduced computational complexity. The multiuser receiver is compatible with ZF-BLE, MMSE, decorrelating detectors and the like using Cholesky decomposition to minimize numeric operations. The receiver and method arranges the columns of system transmission response matrices representing the response characteristics of individual users into a total system transmission response matrix which represents a plurality of matched-filter responses for a given block of received data. The invention when used in conjunction with Cholesky decomposition reduces the number of required mathematic operations prior to parallel matched filtering.

Abstract: En flerbrukerdetektor som detekterer og dekoder synkrone eller asynkrone CDMA-delkanaler med forskjellige spredingsfaktorer med redusert beregningskompleksitet. Foreliggende flerbrukerdetektorer er kompatible med ZF-BLE, MMSE, dekorreleringsdetektorer og liknende ved bruk av Cholesky-dekomponering for å minimalisere numeriske operasjoner. Systemet og fremgangsmåten anordner kolonnene i systemtransmisjonsresponsmatrisene som representerer individuelle brukeres responskarakteristikker i en vel båndet totalsystemtransmisjonsresponsmatrise som representerer flere matchete filterresponser for en gitt blokk av mottatte data. I sammenheng med Cholesky-dekomponering, reduserer oppfinnelsen antallet av nødvendige matematiske operasjoner forut for parallell matchet filtrering.
