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…
New Signal Designs for Enhanced Spatial Modulation
Chien-Chun Cheng, Hikmet Sari, Serdar Sezginer +1
In this paper, we present three new signal designs for Enhanced Spatial Modulation (ESM), which was recently introduced by the present authors. The basic idea of ESM is to convey i…
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…
