Abstract:
1. An MIMO (Multiple Input Multiple Output) receiver for performing channel demultiplexing of data transmitted from a plurality of transmitting antennas and received by a plurality of receiving antennas, comprising: a channel estimator configured to calculate a channel estimate based on the received data; a linear interpolator configured to calculate a plurality of different channel estimates by using the channel estimate output from the channel estimator; a switch configured to select either the channel estimate within a frame from the channel estimator or the different channel estimates within a frame from the linear interpolator based on the number of the plurality of transmitting antennas; and a MIMO demultiplexer configured to perform a MIMO demultiplexing on the received data by using either the channel estimate from the channel estimator or the different channel estimates from the linear interpolator whose applicable data range has been adjusted by both the linear interpolator and the switch.
