Abstract EN
Filter model reduction is an important optimization method in digital signal processing.
A method of FIR to FIR model reduction using SDP optimization is proposed in this paper.
At first, we use SDP to design an original FIR filter.
Then we name a general K-order FIR digital filter H1z−1 with coefficient values equal to the first K + 1 filter coefficient values of H0z−1.
Finally, we design a new general K-order FIR digital filter H2z−1 connected in parallel with H1z−1 using SDP optimization.
The experiment results show this method has good performance on the magnitude error and the linear phase in passband.
Therefore, this method can be used in the field of digital signal processing.
