Belief-Propagation Decoding of LDPC Codes with Variable Node-Centric Dynamic Schedules
Tofar C. -Y. Chang, Pin-Han Wang, Jian-Jia Weng +2
Belief propagation (BP) decoding of low-density parity-check (LDPC) codes with various dynamic decoding schedules have been proposed to improve the efficiency of the conventional f…
Adaptive Group Shuffled Decoding for LDPC Codes
Tofar C. -Y. Chang, Yu T. Su
We propose new grouping methods for group shuffled (GS) decoding of both regular and irregular low-density parity check cods. These methods are independent of the check-to-variable…
Reduced-Rank Channel Estimation for Large-Scale MIMO Systems
Ko-Feng Chen, Yen-Cheng Liu, Yu T. Su
We present two reduced-rank channel estimators for large-scale multiple-input, multiple-output (MIMO) systems and analyze their mean square error (MSE) performance. Taking advantag…
Detection of Spatially-Modulated Signals in Doubly Selective Fading Channels With Imperfect CSI
Hsuan-Cheng Chang, Yen-Cheng Liu, Yu T. Su
To detect spatially-modulated signals, a receiver needs the channel state information (CSI) of each transmit- receive antenna pair. Although the CSI is never perfect and varies in…
Dynamic Weighted Bit-Flipping Decoding Algorithms for LDPC Codes
Tofar C. -Y. Chang, Yu T. Su
Bit-flipping (BF) decoding of low-density parity-check codes is of low complexity but gives inferior performance in general. To improve performance and provide new BF decoder optio…
Composite Channel Estimation in Massive MIMO Systems
Ko-Feng Chen, Yen-Cheng Liu, Yu T. Su
We consider a multiuser (MU) multiple-input multiple-output (MIMO) time-division duplexing (TDD) system in which the base station (BS) is equipped with a large number of antennas f…
