Efficient signal detector design for OTFS with index modulation

Digital Communications and Networks
In this paper, efficient signal detectors are designed for Orthogonal Time Frequency Space (OTFS) modulation with Index Modulation (IM) systems. Firstly, the Minimum Mean Squared Error (MMSE) based linear equalizer and its corresponding soft-aided ...

Doppler-Induced Inter-Carrier Interference Localization in Body Area Network Multicarrier Systems: A Monte Carlo Comparison of OFDM and OCDM Under Rician Multipath

IEEE Access
Body Area Networks (BAN) operate in propagation environments that are both frequency–selective and time–varying due to human motion. Time selectivity within a multicarrier block produces inter–carrier interference (ICI), which limits

Oversampling enhanced receiver method for OFDM systems over time-varying channels

Tongxin xuebao
To address the destruction of subcarrier orthogonality, increased inter-carrier interference (ICI), and the limited performance of conventional frequency-domain equalization caused by orthogonal frequency-division multiplexing (OFDM) spectral broadening ...

RNN based MMSE detection for massive MIMO systems with OTA and imperfect channel state information

Discover Applied Sciences
This study investigated the bit-error-rate (BER) performance of various detection algorithms for massive multiple-input multiple-output (MIMO) systems under realistic channel impairments, including channel estimation errors, Rayleigh fading, and over-the-
