In this paper, we propose a novel deep learning (DL)-based gridless direction-of-arrival (DOA) estimation method for generalized linear arrays using residual attention network (RAN) and transfer (TL). The proposed can improve the DOA performance in both low high signal-to-noise ratio (SNR) regions by focusing on important features input avoiding problems of gradient vanishing degradation. Moreover, introduce idea TL to reduce complexity costs training. experimental results demonstrate...
Acoustic cameras have found many applications in practice. Accurate and reliable extrinsic calibration of the microphone array visual sensors within acoustic is crucial for fusing auditory measurements. Existing methods either require prior knowledge geometry or rely on grid search which suffers from slow iteration speed poor convergence. To overcome these limitations, this paper, we propose an automatic technique using a board with both markers to identify each position camera frame. We...
The background that underlies this work is the envisioned real-time tele-immersive collaboration system for future supports delay-sensitive applications involving participants from remote places via their spaces (CSs). end-to-end delay as high 20 ms required good synchronization of such applications, example collaborative dancing and conducting choir. It much lower than facilitated by existing teleconference systems. A novel network architecture with guarantee, namely Distributed Multimedia...
Design and functional implementation of a 16-point pipelined FFT architecture is presented.The based on the radix-4 algorithm.By exploiting regularity algorithm, butterfly operation multiplier modules were designed.The adopts four butterflies, pipeline stage optimized to balance processing speed area.It was modeled by VHDL, synthesized in FPGA.By adopting this architecture, data throughput could be 2M/s.It extensible for high point FFT.
