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, including a retransmission control function for carrying out said decode process in use of said second channel reception signal and a retransmission signal of the reception signal, said apparatus comprising: a channel compensation processor configured to carry out a channel compensation process on said first channel reception signal in use of the channel estimation value obtained for said first channel reception signal based on a plurality of known signals received from the base station apparatus; and a channel re-compensation processor configured to carry out the channel compensation process again on said first channel reception signal with said channel estimation value of said first channel reception signal obtained based on a plurality of known signals including at least a known signal which is received after reception of said first channel reception signal when a decoding result of said first channel reception signal after the channel compensation process by the channel compensation processor is defined as an error.
