Non-binary coded CCSK and Frequency-Domain Equalization with simplified LLR generation
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)
In this paper, we investigate the performance of Single-Carrier (SC) transmission with Non-Binary Low-Density Parity-Check (NB-LDPC) coded Cyclic Code-Shift Keying (CCSK) signaling in a multipath environment and we show that the combination of CCSK signaling and non-binary codes results in two key advantages, namely, improved Log-Likelihood Ratio (LLR) generation via correlations and reduced implementation complexity. We demonstrate that Maximum Likelihood (ML) demodulation can be expressed bydoi:10.1109/pimrc.2013.6666375 dblp:conf/pimrc/AbassiCMB13 fatcat:zpal6y7bsbdgbklenplf3vmi3e
