Link-Level Performance Evaluation of IMT-2020 Candidate Technology: DECT-2020 New Radio
Maxim Penner, Muhammad Nabeel, Jürgen Peissig
The ETSI has recently introduced the DECT-2020 New Radio (NR) as an IMT-2020 candidate technology for the mMTC and URLLC use cases. To consider DECT-2020 NR as an IMT-2020 technolo…
Direction of Arrival Estimation of Noisy Speech Using Convolutional Recurrent Neural Networks with Higher-Order Ambisonics Signals
Nils Poschadel, Robert Hupke, Stephan Preihs +1
Training convolutional recurrent neural networks on first-order Ambisonics signals is a well-known approach when estimating the direction of arrival for speech/sound signals. In th…
Joint Channel Estimation and Data Decoding using SVM-based Receivers
