Receiving apparatus and transmitting-receiving apparatus
Abstract:
A receiving apparatus includes: a control signal channel estimator to estimate a channel for a control signal using a pilot signal extracted from a received signal, and generate a first channel estimate value; a control signal FED unit to perform frequency domain equalization processing on the control signal by using the first channel estimate value; a control signal demodulator to demodulate the equalized control signal; a control signal encoder to encode a demodulated equalized control signal; an FFT unit to generate, from the encoded equalized control signal, a control signal replica; a data channel estimator to estimate a channel for the data signal by using the control signal replica and the first channel estimate value; and a data FDE unit to perform frequency domain equalization processing on the data signal by using the second channel estimate value.
