Coefficient quantization in perfect-reconstruction cosine-modulated filter banks

This paper analyzes perfect-reconstruction (PR) cosine-modulated filter banks (CMFBs) from the quantization point of view. We study how the straightforward coefficient quantization affects on the performance of the transmultiplexer (TMUX) systems. In this paper, TMUX implementation is based on the structure of fast extended lapped transform (ELT). The quantized TMUX systems are analyzed in terms of stopband attenuation, intercarrier interference (ICI), and intersymbol interference (ISI).
