Linear Precoding Design for OTFS Systems in Time/Frequency Selective Fading Channels
Yao Ge, Lingsheng Meng, David González G. +3
Even orthogonal time frequency space (OTFS) has been shown as a promising modulation scheme for high mobility doubly-selective fading channels, its attainability of full diversity…
