The configurable structure for Discrete Hilbert Transform via systolic array

A novel configurable systolic array for Discrete Hilbert Transform (DHT) with any number of sample points is proposed for the applications, which have distinct number of the samples in different cases such as filter in Katsevich formula for cone-beam computed tomography (CBCT). The proposed array is based on the configurable matrix formulation of DHT, and it performs different procedure by the configurable number of samples N. Simulation results shows that the array is most efficient when the matrix of the configurable matrix formulation of DHT can partition in to less than 32 partitions.
