Superposition Coding-Assisted DFT-s-OFDM: A Trade-off Between PAPR and Spectral Efficiency

Fifth-generation (5G) communication systems employ orthogonal demodulation reference signals to eliminate pilot contamination and user interference, resulting in a significant overhead for reserving resource elements in the time-frequency grid. 5G technologies rely on orthogonal frequency division multiplexing (OFDM) a...
