Abstract
This paper introduces a multi-user uplink system, utilizing the orthogonal time frequency space (OTFS) modulation scheme. The proposed design employs the generalized singular value decomposition (GSVD) of the channels connecting the base station and the two users. Precoding and detection matrices are constructed using the right and left singular vectors, respectively. Analytical expressions are derived for a practical antenna configuration, and corresponding simulation results are presented. Simulation results for uncoded, coded, and coded scenarios with channel estimation errors reveal that the proposed GSVD-based approach outperforms MMSE equalization in certain antenna configurations. Notably, GSVD shows advantages under channel estimation error in the coded scenario.
