B-Splines

High-Performance Vectorized Cubic B-Spline Interpolation Algorithms

At EMS we conduct extensive radio measurement campaigns, which are the basis for future radio standards. This measurement data boils down to gigabytes per second of raw data collected over hours of measurement campaigns 1. Afterwards, we can compute the estimated radio channel parameters from those measurements. A major bottleneck is the interpolation of the measured antenna characteristic 2. Hence, we wish to improve compute throughput by using vectorized computation. This research project will give insights to how our existing algorithms could be vectorized on the tu ilmenau cpu hpc cluster.
