Low-Complexity Linear Diversity-Combining Detector for MIMO-OTFS
In the proposed detector, the copies of the transmitted symbol-vectors received through the different diversity branches (propagation paths and receive antennas) are linearly combined using the maximum ratio combining (MRC) technique to iteratively improve the signal to interference plus noise ratio (SINR) at the output of the combiner.
Unitary-Precoded Single-Carrier Waveforms for High Mobility: Detection and Channel Estimation
This paper presents unitary-precoded single-carrier (USC) modulation as a family of waveforms based on multiplexing the information symbols on time domain unitary basis functions.
Orthogonal Time Sequency Multiplexing Modulation: Analysis and Low-Complexity Receiver Design
This paper proposes orthogonal time sequency multiplexing (OTSM), a novel single carrier modulation scheme that places information symbols in the delay-sequency domain followed by a cascade of time-division multiplexing (TDM) and Walsh-Hadamard sequence multiplexing.
Low Complexity Iterative Rake Decision Feedback Equalizer for Zero-Padded OTFS systems
We further propose a Gauss-Seidel based over-relaxation parameter in the rake detector to improve the performance and the convergence speed of the iterative detection.
