A Review of FIR Filter Designs

Interfaz cerebro-computadora para la codificacion de clave morse mediante señales cerebrales

“…Generalmente el filtrado digital se realiza con un filtro de respuesta finita (FIR), cuya salida se calcula con (1). Donde el valor de 𝑁𝑁 es el orden del filtro, los valores de C k 𝐶𝐶 𝑘𝑘 n los coeficientes del filtro, mientras que 𝑋𝑋 𝑗𝑗 y 𝑌𝑌 𝑗𝑗 son los j-ésimos términos de entrada y salida, respectivamente (Bansal et al, 2018):…”

Waveform Design for 5G and beyond Systems

“…In Reference [54], the methods of prototype filter design for cosine modulated filter banks (CMFBs) with nearly perfect reconstruction (NPR) are reviewed by K. Shaeen et al, and these methods are categorized into nonlinear optimization methods [55][56][57][58][59][60][61][62][63], spectral factorization methods [64], linear search methods [65][66][67][68][69][70], interpolated finite impulse response (IFIR) methods [71][72][73], and frequency response masking (FRM) methods [58,[74][75][76][77][78][79], and so forth. The authors of Reference [80] provide the basic introduction of the FIR filter, some relevant works on FIR and various factors which effect the performance of FIR filter in communication systems.…”

“…In this paper, we pay more attention to the literature from more recent years and provide a survey on various FIR filter design methods in multicarrier systems. Compared with the existing surveys in References [4,54,80], this paper provides an in-depth introduction to advanced filter design methods, which are not categorized based on the design criteria. In addition, this work can serve as an extension of the survey in Reference [54], which is dedicated to the aspect of CMFBs.…”
