INTERPOLATING METHOD FOR AN OFDM SYSTEM AND CHANNEL ESTIMATION METHOD AND APPARATUS |
摘要 |
The present invention provides an interpolating method for an OFDM system, a channel estimation method and apparatus, in which each OFDM symbol has scattered pilots inserted, and the interpolating method comprising: the step (S602) of inserting at least one copy of the first scattered pilot in each OFDM symbol before the first scattered pilot as virtual pilots, and inserting at least one copy of the last scattered pilot in each OFDM symbol behind the last scattered pilot as virtual pilots, after obtaining the channel state information on the sub channels which propagate the scattered pilots in the OFDM symbols by linear filtering; and the step (S604) of performing interpolation by a FIR filter with the channel state information.
