Implementation of the precoder matrix indicator selection using MMSE trace criterion for the downlink transmission in LTE

Chang-Han Chung, Tsung-Hsien Liu, Yuan-Sun Chu

ICASSP 2016accepted

Based on the minimum mean squared error (MMSE) trace criterion, selection of the precoding matrix indicator (PMI) from the downlink codebook of the LTE system is considered in this paper. Due to the codebook of 16 member precoding matrices and up to 1200 sub-carriers in this MIMO-OFDM system, the PM…

Implementation of the SVD-based precoding sub-system for the compressed beamforming weights feedback in IEEE 802.11n/ac WLAN

Yang-Cheng Lin, Tsung-Hsien Liu, Chia-Peng Chou, Yuan-Sun Chu

ICASSP 2015accepted

The compressed beamforming weights feedback is used in the precoded MIMO-OFDM system, e.g., IEEE 802.11n/ac WLAN, to reduce the amount of feedback information. The precoded sub-system at the receiver of this system needs to perform singular value decomposition (SVD) on the estimated channel matrices…
