RADIO RECEIVER APPARATUS AND RADIO TRANSMITTER APPARATUS |
摘要 |
<p>A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.</p> |
