Abstract :
Computation of Wideband Coherent Signal-Subspace (CSS) Based Direction of Arrival (DOA) has been parallelized and implemented on Multicore (Intel Nehalem Quad Core) and NVIDIA´s GPU. This is in an effort to its use for real time applications. The CSS algorithm has been parallelized, partitioned, mapped and scheduled on Multi-Core/GPU. The parallel algorithm is developed in C# and a combination of C and CUDA for Multi-Core and GPU respectively. The algorithm has also been implemented on single core for comparison purposes. Wideband CSS algorithm is implemented assuming 16 and 4 sensors using Uniform Linear Array (ULA).
