Abstract

This paper considers perfect reconstruction lattice filter banks. When optimizing for coding gain the purpose is to find a simple perfect reconstruction structure with few multiplication and reasonable gain. We present such a system which also possesses a certain regularity when expanding from N to 2N channels. Results including both obtained gain and the number of filter multiplications and filter magnitude responses are presented. The results show that the system gives strange filter responses, but good coding gain considering the number of multiplications.
