    • PROBLEM TO BE SOLVED: To provide a communication device which is capable of reducing an operation amount required to separate multiple transmission signals based on multiple reception signals received through multiple antennas.SOLUTION: A communication device 3 obtains a residual component which is obtained by removing a component corresponding to other transmission signal candidates except a predetermined transmission signal among multiple transmission signals from a signal corresponding to any of multiple reception signals; by making the closest value to the residual component among values the predetermined transmission signal can take as a candidate of the predetermined transmission signal, and by making collection of a pair of the candidate of the predetermined transmission signal and a candidate of another transmission signal as a candidate group, obtains multiple candidate groups by changing the predetermined transmission signals; by selecting a pair of transmission signal candidates common to multiple candidate groups, and calculating a distance between a pair of estimated reception signals corresponding to the pair of transmission signal candidates and the multiple reception signals regarding each of selected pairs of transmission signal candidates, and estimates a pair of transmission signal candidates which has the shortest distance as multiple pairs of transmission signals.
    • 要解决的问题:提供一种能够基于通过多个天线接收的多个接收信号来减少分离多个发送信号所需的操作量的通信装置。 解决方案:通信设备3获得通过从与多个接收信号中的任何一个相对应的信号中去除与多个发送信号之中的预定发送信号之外的其他发送信号候选相对应的分量而获得的残差分量; 通过在预定的传输信号可以作为预定的传输信号的候选值的值中与残差分量最接近的值,并且通过将预定传输信号的候选对和另一个传输信号的候选作为一个 候选组,通过改变预定的传输信号来获得多个候选组; 通过选择与多个候选组共同的一对发送信号候补,并计算与一对发送信号候选对应的一对估计接收信号和关于每个所选择的发送信号候选对中的多个接收信号之间的距离,以及估计 具有最短距离的一对发送信号候选作为多对发送信号。 版权所有(C)2012,JPO&INPIT
