Adaptive zero padded CB-FMT for LTE uplink transmission in the high mobility scenario. Girotto, M. & Tonello, A. M. In 2017 25th European Signal Processing Conference (EUSIPCO), pages 878-882, Aug, 2017. Paper doi abstract bibtex LTE is the most recent standard for the mobile cellular communication. To achieve high speed communications, multi-carrier modulations have been adopted both for the downlink and the uplink. In the LTE downlink, OFDMA (the multi-user version of OFDM) has been chosen. The LTE uplink uses instead SC-FDMA modulation, an OFDM alternative. In this work, the use of CB-FMT, jointly with SC-FDMA, is analyzed in the high mobility scenario. Numerical results show that CB-FMT outperforms SC-FDMA in several cases. Thus, an adaptive implementation architecture that allows to flexibly choose the modulation scheme is proposed to maximize the achievable rate. Furthermore, for compliance with existing LTE parameters, frequency domain zero padded CB-FMT is proposed, and the problem of designing optimal capacity wise waveforms is considered.
