Title:
RECEIVING DEVICE, RECEIVING METHOD AND RECEIVING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/121958
Kind Code:
A1
Abstract:
A GI removing unit (b102-nR) removes a GI from a received signal. An FFT unit (b103-nR) performs time frequency conversion on a signal received in step S101. A demapping unit (b104-nR) separates, from the signal of a frequency region that can be obtained, the received signal of resource elements for which data, a first pilot symbol and a second pilot symbol are transmitted. A pass extraction unit (b105-nR) uses the first pilot symbol to extract a pass valid for estimation. A propagation path estimation unit (b106-nR ) calculates a first CFR estimation value using the second pilot symbol, calculates a CIR estimation value using pass position information extracted by the pass extraction unit and the first CFR estimation value, and thereafter converts the calculation results to a second CFR estimation value.
