Deep Reinforcement Learning-aided Transmission Design for Energy-efficient Link Optimization in Vehicular Communications
This letter presents a deep reinforcement learning (DRL) approach for transmission design to optimize the energy efficiency in vehicle-to-vehicle (V2V) communication links.
GI-Free Pilot-Aided Channel Estimation for Affine Frequency Division Multiplexing Systems
The recently developed affine frequency division multiplexing (AFDM) can achieve full diversity in doubly selective channels, providing a comprehensive sparse representation of the delay-Doppler domain channel.
A Low-Complexity Range Estimation with Adjusted Affine Frequency Division Multiplexing Waveform
Affine frequency division multiplexing (AFDM) is a recently proposed communication waveform for time-varying channel scenarios.
Digital Self-Interference Cancellation With Robust Multi-layered Total Least Mean Squares Adaptive Filters
In each layer, our proposed m-MTLS estimator first employs an M-estimate total least mean squares (MTLS) algorithm to eliminate residual SI from the received signal and give a new estimation of the RT channel.
A Phase-Coded Time-Domain Interleaved OTFS Waveform with Improved Ambiguity Function
To enhance the sensing performance of the orthogonal time frequency space (OTFS) waveform, we propose a novel time-domain interleaved cyclic-shifted P4-coded OTFS (TICP4-OTFS) with improved ambiguity function.
An Overview of Resource Allocation in Integrated Sensing and Communication
Integrated sensing and communication (ISAC) is considered as a promising solution for improving spectrum efficiency and relieving wireless spectrum congestion.
Overview and Performance Analysis of Various Waveforms in High Mobility Scenarios
In the high-mobility scenarios of next-generation wireless communication systems (beyond 5G/6G), the performance of orthogonal frequency division multiplexing (OFDM) deteriorates drastically due to the loss of orthogonality between the subcarriers caused by large Doppler frequency shifts.
Cyclic Delay-Doppler Shift: A Simple Transmit Diversity Technique for Delay-Doppler Waveforms in Doubly Selective Channels
Delay-Doppler waveform design has been considered as a promising solution to achieve reliable communication under high-mobility channels for the space-air-ground-integrated networks (SAGIN).
Pilot Aided Channel Estimation for AFDM in Doubly Dispersive Channels
Affine frequency division multiplexing (AFDM) is a multi-chirp waveform and a promising solution for ultra-reliable communication under doubly dispersive channels.
