Abstract
By precoding multiple data bocks before cyclic-prefixed orthogonal frequency-division multiplexing (CP-OFDM) modulation, the rectangularly-pulsed CP-OFDM frame modulation structure has been adopted to achieve better error performance than CP-OFDM over linear time-varying multipath (LTV) channels. Typical embodiments include cyclic-preflxed orthogonal time frequency space (CP-OTFS), cyclic-preflxed orthogonal time sequency multiplexing (CP-OTSM), cyclic-preflxed affine frequency division multiplexing (CP-AFDM), cyclic-preflxed single carrier (CP-SC), and cyclic-preflxed anchor-aided single carrier (CP-ASC). These CP-OFDM frame modulations show various desirable but not simultaneously existing features, including resistance to double channel dispersion, low peak-to-average power ratio (PAPR), and high spectral compactness. By incorporating anchor-symbol insertion, selected mapping, and uniform data spreading into the CP-OFDM frame modulation structure, cyclic-preflxed anchor-aided time sequency multiplexing (CP-ATSM) is proposed in this paper. CP-ATSM performs comparably with CP-OTFS and CP-OTSM and outperforms CP-AFDM, CP-SC, and CP-ASC in uncoded error performance over LTV channels, while offering reduced PAPR compared to CP-OTFS, CP-OTSM, and CP-AFDM. Besides, CP-ATSM performs comparably with CP-ASC and outperforms CP-OTFS, CP-OTSM, CP-AFDM, and CP-SC significantly in spectral efficiency.
