Vector Approximate Message Passing based Channel Estimation for MIMO-OFDM Underwater Acoustic Communications

no code implementations22 Nov 2022 Wenxuan Chen, Jun Tao, Lu Ma, Gang Qiao

Accurate channel estimation is critical to the performance of orthogonal frequency-division multiplexing (OFDM) underwater acoustic (UWA) communications, especially under multiple-input multiple-output (MIMO) scenarios.

A Lite Microphone Array Beamforming Scheme with Maximum Signal-to-Noise Ratio Filter

no code implementations19 May 2020 Lu Ma, Xin Zhao, Pei Zhao, Tengrong Su

Since space-domain information can be utilized, microphone array beamforming is often used to enhance the quality of the speech by suppressing directional disturbance.
