Abstract: The present invention relates to a method for extracting channel state information (CSI) in a multiple-input multiple-output (MIMO) receiver used in a wireless communication system. According to the present invention, the method comprises the steps of: obtaining an effective channel matrix by multiplying a channel estimation value, obtained through a reference signal for generating channel information, and a preprocessing matrix; calculating an upper limit value and a lower limit value of a minimum distance for each layer by QR decomposition of the effective channel matrix; and mapping the upper and lower limit values of the minimum distance for each layer to each codeword and extracting a mean mutual information per bit (MMIB) metric, which is a transmission capacity per unit frequency, for each codeword. According to the present invention, it is possible to extract CSI with much less operation than the conventional method when the MIMO transmission order is high by using the QR decomposition and the MMIB metric so that the minimum distance for each layer can be obtained without the need for a multidimensional search process.

Title: Method and apparatus for generating reconstruction block
Inventor: PARK SHIN JI
IPC: H04N19/124
Filed: 2019-07-24
Abstract: A method for generating a reconstructed block according to the present invention comprises: decoding an intra prediction mode by using a received intra prediction mode group indicator and a prediction mode index; generating a prediction block according to the intra prediction mode; dequantizing a received residual signal using a quantization parameter; generating a residual block by being adaptively inverse-transformed according to intra prediction mode; and generating a reconstructed block by adding the prediction block and the residual block. The quantization parameter is reconstructed according to the information indicating the received minimum quantization CU size. The information indicating the minimum quantization CU size is determined by a parameter transmitted from a picture parameter set. Accordingly, the video quality can be improved by adaptively adjusting the quantization parameter according to the coding size. In addition, the number of bits required to transmit the quantization parameter is reduced by effectively encoding/decoding the quantization parameter so the video compression efficiency can be improved.
