Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The cosine-modulated filter bank (CMFB) is an attractive filter bank structure with a simplified design, being based on a single prototype filter. Recent advances have reduced the overall CMFB computational cost by employing the frequency-response masking (FRM) approach to design the prototype filter. The present paper discusses the use of recurrent-FRM stages to design CMFBs. It is verified how by applying several layers of the FRM method can further reduce the computational complexity of resulting CMFB structures. This technique also yields a simpler procedure when one is interested on optimizing the CMFB performance with respect to practical figures-of-merit such as the intersymbol interference (ISI) and interchannel interference (ICI).
