Title:
RECEPTION DEVICE AND METHOD FOR RECEIVING MIMO-OFDM SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/049050
Kind Code:
A1
Abstract:
A reception device is disclosed. One embodiment may comprise: determining a channel estimation sequence of OFDM symbols in which data symbols are transmitted; determining a channel prediction value for a first OFDM symbol in a first channel estimation sequence among the OFDM symbols using at least one of reference signal-based channel estimation information and channel estimation information determined before the first channel estimation sequence; detecting first data symbols from a received signal at the first OFDM symbol using the determined channel prediction value; determining a first channel estimate value for the first OFDM symbol on the basis of the detected first data symbols; determining a second channel estimate value for the first OFDM symbol on the basis of the determined first channel estimate value and the determined channel prediction value; determining whether the first channel estimation sequence is the last channel estimation sequence; and if the first channel estimation sequence is not the last channel estimation sequence, performing channel estimation for a second OFDM symbol in the next channel estimation sequence.
