Efficient systolic implementation of complex digital filters
Daka Raghuramireddy, Rolf Unbehauen · Electronics Letters · 1991
A systolic structure is proposed for the implementation of complex recursive digital filters which alternately produce the real and imaginary parts of the output in a sequence. This structure possesses a large degree of modularity, regularity, parallelism and amenability to the VLSI design and requires half of the number of the processing elements normally required.
