    • PURPOSE: A CDMA mobile station device is provided to enhance the accuracy of demodulation of a data signal when wirelessly receiving a control spread signal and a data spread signal from a device of a base station. CONSTITUTION: Non-orthogonal spread signal generating means(4-5) use a non-orthogonal spread code to generate a non-orthogonal spread signal whose phase rotation in a wireless transmission line is compensated, subtraction means(7,8) subtract the generated non-orthogonal spread signal from a received signal as an interference signal and data signal demodulation means(9,10) use the data signal use spread code to demodulate the data signal from the result of subtraction of the subtraction means. Furthermore, there are other configurations as a configuration to eliminate an entire notice signal, a configuration corresponding to a band limit and a configuration employing a suppression coefficient.
    • 目的:提供一种CDMA移动站装置,用于当从基站的设备无线地接收控制扩展信号和数据扩展信号时,提高数据信号的解调精度。 构成:非正交扩展信号发生装置(4-5)使用非正交扩展码来产生其无线传输线中的相位旋转被补偿的非正交扩展信号,减法装置(7,8)减去所产生的 来自作为干扰信号的接收信号的非正交扩展信号和数据信号解调装置(9,10)使用数据信号使用扩展码从减法装置的减法结果中解调数据信号。 此外,作为用于消除整个通知信号的配置,对应于频带限制的配置以及采用抑制系数的配置,还有其他配置。
