Communication device and method for receiving a signal

摘要

A communication device is described comprising a plurality of receive paths, wherein each of the plurality of receive paths is configured to extract a multipath component of a received signal, a determiner configured to determine whether at least two of the plurality of receive paths fulfil a mutual interference correlation criterion among the plurality of receive paths and a processor configured, if at least two of the plurality of receive paths fulfil the interference correlation criterion among the plurality of receive paths, to determine the sent signal based on canceling or mitigating the interference between the multipath components of the received signal extracted by the at least two receive paths.

1. A communication device comprising:
a plurality of receive paths, wherein each of the plurality of receive paths is configured to extract a multipath component of a received signal; a determiner configured to determine whether at least two of the plurality of receive paths fulfill a mutual interference correlation criterion among the plurality of receive paths; and a processor configured, if at least two of the plurality of receive paths fulfill the interference correlation criterion among the plurality of receive paths, to group at least two multipath components and an interference signal into a subset and to cancel or mitigate the subset based on the mutual interference correlation; wherein the mutual interference correlation criterion is at least one selected from the group consisting of:
whether a symmetric timing relation exists between an interference signal, a multipath component extracted by one receive path of the plurality of receive paths and a multipath component extracted by another receive path of the plurality of receive paths;whether a sender of the sent signal has a symmetric delay profile with respect to the multipath components or whether another sender sending an interference signal has a symmetric delay profile with respect to the multipath components; orwhether a difference between the time of arrival of an interference signal at a first receive path of the plurality of receive paths and the time of arrival of an interference signal at a second receive path of the plurality of receive paths is within a predetermined range of a propagation delay difference between the multipath components of the first receive path and the second receive path.
