What is Parallel Computing in Signal Processing?
Parallel Computing in Signal Processing optimizes signal processing algorithms for parallel architectures like GPUs to handle high-dimensional data in real-time cyber-physical systems.
This subtopic focuses on parallelizing spectral analysis, neural network training, and radar signal recognition for scalable performance. Key works include Goolak et al. (2021) on spectral analysis of traction currents (18 citations) and Matuszewski and Pietrow (2021) on CNN-based radar recognition (20 citations). Over 10 papers from 2019-2023 address scalability in distributed systems.
Why It Matters
Parallel computing enables real-time processing in cyber-physical systems, such as AC electric locomotives where Goolak et al. (2021) improved spectral analysis under voltage fluctuations. In radar systems, Matuszewski and Pietrow (2021) used CNNs on parallel hardware for waveform recognition amid electromagnetic interference. Alexandrov et al. (2023) applied genetic algorithms for neural network optimization, supporting big data in industrial controls (17 citations).
Key Research Challenges
Scalability on GPUs
Adapting sequential signal algorithms to GPU parallelism faces memory bottlenecks and synchronization overheads. Suleimenov et al. (2022) highlight distributed memory limits in neural networks for signal tasks (23 citations). Benchmarks show linear speedup degrades beyond 64 cores.
Real-time Latency
Meeting CPS deadlines requires minimizing parallel overhead in high-dimensional signals. Goolak et al. (2021) address non-deterministic voltage changes in traction current analysis (18 citations). Deterministic scheduling remains unsolved for variable workloads.
Data Distribution
Partitioning big data arrays hierarchically challenges control systems. Reut et al. (2019) propose lifeworld-based scaling for industrial complexes (21 citations). Load imbalance persists in heterogeneous architectures.
