Abstract :
The optimization of subband coders for specific input statistics has been an interesting problem for quite some time. For orthonormal filter banks with infinite order and uniform decimation, this problem has been completely solved in recent years. For the case of biorthogonal filter banks significant progress has been made recently, though a number of issues still remain to be addressed. In this paper we present several new results for the biorthogonal case. All discussions are for infinite order (ideal) filters
