Implementation of raised cosine filters using orthonormal expansions
Giridhar D. Mandyam · 2002
Discrete-time sequences, in particular Laguerre sequences, are effective for representing sequences in the form of orthogonal expansions. Taking advantage of the network realization of a Laguerre expansion, it is shown that approximating raised-cosine filters by means of Laguerre expansions provides considerable savings in hardware implementations without adding significant distortion.
