A Low-Complexity Joint Fractional Delay and Doppler Frequency Estimator for AFDM-Enabled Vehicular LEO-ICAN Systems
Zhenyu Chen, Ke Xiao, Xiaomei Tang +3
Low-Earth-orbit (LEO) satellites and vehicle-to-everything (V2X) networks are driving integrated communication and navigation (ICAN) toward next-generation intelligent transportati…
On Optimizing Hierarchical Modulation in AWGN channel
Baicen Xiao, Kexin Xiao, Zhiyong Chen +1
Hierarchical modulation (HM) is able to provide different levels of protection for data streams and achieve a rate region that cannot be realized by traditional orthogonal schemes,…
Iterative detection and decoding for SCMA systems with LDPC codes
Baicen Xiao, Kexin Xiao, Shutian Zhang +3
Sparse code multiple access (SCMA) is a promising multiplexing approach to achieve high system capacity. In this paper, we develop a novel iterative detection and decoding scheme f…
Simplified Multiuser Detection for SCMA with Sum-Product Algorithm
Kexin Xiao, Baicen Xiao, Shutian Zhang +2
Sparse code multiple access (SCMA) is a novel non-orthogonal multiple access technique, which fully exploits the shaping gain of multi-dimensional codewords. However, the lack of s…
