Abstract:
1. A mobile terminal apparatus for decoding a first channel reception signal received from a base station apparatus after a channel compensation process in use of a channel estimation value so as to carry out a decode process on a second channel reception signal received from the base station apparatus in use of the decoding result of the first channel reception signal, wherein a period of time from a completion of receiving said second channel reception signal to a completion of decoding the second channel reception signal is regulated as a predetermined time, said apparatus comprising: a channel estimation processor configured to obtain the channel estimation value of said first channel reception signal by using a plurality of known signals received from the base station apparatus within a channel estimation period; a channel compensation processor configured to carry out a channel compensation process of said first channel reception signal by using the channel estimation value obtained by said channel estimation processor; and a controller configured to control said channel estimation period so as to include a known signal which is received after the reception of said first channel reception signal for channel compensation into said plurality of known signals in accordance with remaining time from completion of the decoding process on said second channel reception signal until the end of said predetermined time.
