Abstract
In the present disclosure, the UE apparatus is classified by type and the demodulation information to use in channel estimation of MUI signals is determined based on the type of the UE apparatus. The channel estimating apparatus for MUI signals has: a user type determining circuit that determines whether a UE apparatus corresponding to an own station belongs to a first type user or a second type user and determines demodulation information to use in channel estimation of MUI signals based on the type of the UE apparatus corresponding to the own station; and a channel estimating circuit that performs channel estimation of a multi-user interference signal based on the determined demodulation information to use in channel estimation of MUI signals. With this structure, it is possible to improve channel estimation accuracy and further to improve the performance of data reception and user and cell throughputs.
