    • CDMA Receiver. According to one embodiment, a CDMA receiver is provided for receiving a CDMA signal in a multi-subscriber environment. The multi-subscriber environment can include a receiving device for receiving the CDMA signal. Further, the environment can include a Rake receiving circuit for detection of signal components of the CDMA signal which are transmitted via the various signal paths. The environment can also include a channel estimation circuit for estimating channel coefficients of a transmission channel coefficient h of a transmission channel H by means of a predetermined reference data sequence contained in the received CDMA signal. A weighting coefficient calculation device can calculate weighting coefficients for the various signal components of the CDMA signal. Further, the environment can include a weighting circuit for weighting the signal components with the calculaed weighting coefficients. A combiner can combine the weighted signal components to form an estimated received data signal.
    • CDMA接收机。 根据一个实施例,提供CDMA接收机用于在多用户环境中接收CDMA信号。 多用户环境可以包括用于接收CDMA信号的接收设备。 此外,环境可以包括用于检测通过各种信号路径发送的CDMA信号的信号分量的耙式接收电路。 环境还可以包括用于通过包含在所接收的CDMA信号中的预定参考数据序列来估计传输信道H的传输信道系数h的信道系数的信道估计电路。 加权系数计算装置可以计算CDMA信号的各种信号分量的加权系数。 此外,环境可以包括用于利用计算的加权系数对信号分量进行加权的加权电路。 组合器可以组合加权信号分量以形成估计的接收数据信号。
