Transmit Diversity Scheme Design for Rectangular Pulse Shaping Based OTFS
文献摘要:
This paper investigates the transmis-sion scheme of the orthogonal time frequency space(OTFS)system with multiple antennas.Previous works have studied the multi-antenna transmitter di-versity scheme with the ideal pulse shaping in OTFS systems assuming the wireless channels of two con-secutive frames duration are invariant.However,the ideal pulse shaping can not be realized in practice and the channel varies rapidly in two consecutive frames in the high-speed mobility scenarios.To this end,we re-design the multi-antenna transmitter diversity scheme to ensure its practicability in the rectangular-pulse-based OTFS systems.At first,the information sym-bols of each antenna are divided into two half frames along the Doppler domain.Then,the guard symbols are carefully arranged to eliminate the interference be-tween two half frames,and to ensure the equivalent channels of two half frames being identical.By con-sidering the positions of the guard symbols,the trans-mission codeword is designed and a low complexity linear detection is proposed.Finally,simulation re-sults validate that the bit error rate performance of the proposed scheme has the superiority over the existing works.
