OFDM RECEIVER, INTEGRATED CIRCUIT AND RECEIVING METHOD |
摘要 |
<p>To improve the reception performance of a mobile receiver for a digital broadcasting by OFDM method, the present invention focuses on the arrangement of the SP signals. The present invention performs oblique interpolation in such a direction that a symbol number increases by one and a carrier number decreases by three with respect to a position of each Scattered Pilot Signal to interpolate a first signal whose channel characteristics have not been obtained, and then performs, in a frequency axis direction, frequency axis interpolation to interpolate channel characteristics of a second signal whose channel characteristics have not been obtained, using the estimated channel characteristics and the interpolated channel characteristics.</p> |
