Cell-Free Massive MIMO Meets OTFS Modulation [PDF]
IEEE Transactions on Communications, 2022 We provide the first-ever performance evaluation of orthogonal time frequency space (OTFS) modulation in cell-free massive multiple-input multiple-output (MIMO) systems. To investigate trade-off between performance and overhead, we apply embedded pilot-aided and superimposed pilot-based channel estimation methods.
