Performance Analysis and Approximate Message Passing Detection of Orthogonal Time Sequency Multiplexing Modulation
Zeping Sui, Shefeng Yan, Hongming Zhang +4
In orthogonal time sequency multiplexing (OTSM) modulation, the information symbols are conveyed in the delay-sequency domain upon exploiting the inverse Walsh Hadamard transform (…
Subband Random Sensing Grant Free Uplink for URLLC in Unlicensed Spectrum
Yonghong Zeng, Yuhong Wang, Sumei Sun +1
In this paper, we propose a novel scheme called subband random sensing (SRS) grant free uplink for ultra-reliable low-latency communication (URLLC) in unlicensed spectrum. The SRS…
On the Performance of Spectrum Sensing Algorithms using Multiple Antennas
Ying-Chang Liang, Guangming Pan, Yonghong Zeng
In recent years, some spectrum sensing algorithms using multiple antennas, such as the eigenvalue based detection (EBD), have attracted a lot of attention. In this paper, we are in…
Spectrum Sensing Algorithms for Cognitive Radio Based on Statistical Covariances
Yonghong Zeng, Ying-Chang Liang
Spectrum sensing, i.e., detecting the presence of primary users in a licensed spectrum, is a fundamental problem in cognitive radio. Since the statistical covariances of received s…
Eigenvalue based Spectrum Sensing Algorithms for Cognitive Radio
Yonghong Zeng, Ying-Chang Liang
Spectrum sensing is a fundamental component is a cognitive radio. In this paper, we propose new sensing methods based on the eigenvalues of the covariance matrix of signals receive…
