2D-RC: Two-Dimensional Neural Network Approach for OTFS Symbol Detection

no code implementations14 Nov 2023 Jiarui Xu, Karim Said, Lizhong Zheng, Lingjia Liu

Orthogonal time frequency space (OTFS) is a promising modulation scheme for wireless communication in high-mobility scenarios.

Towards Explainable Machine Learning: The Effectiveness of Reservoir Computing in Wireless Receive Processing

no code implementations8 Oct 2023 Shashank Jere, Karim Said, Lizhong Zheng, Lingjia Liu

With this groundwork, we incorporate the available domain knowledge in the form of the statistics of the wireless channel directly into the weights of the ESN model.

Universal Approximation of Linear Time-Invariant (LTI) Systems through RNNs: Power of Randomness in Reservoir Computing

no code implementations4 Aug 2023 Shashank Jere, Lizhong Zheng, Karim Said, Lingjia Liu

Our work results in clear signal processing-based model interpretability of RC and provides theoretical explanation/justification for the power of randomness in randomly generating instead of training RC's recurrent weights.
