摘要：

This paper presents a narrow-band bandpass FIR filter design with a small number of multipliers per output sample (NMPS). The proposed method is based on the use of the Pipelining/Interleaving (PI) technique within a quadrature modulation structure, where only one narrow-band lowpass filter is required. In order to reduce the NMPS, the narrow-band lowpass filter is designed with an Interpolated Finite Impulse Response (IFIR) filter. Then interpolating filter is implemented by using the Sharpened Cascade Integrator Comb (CIC) filter. This results in considerable reduction of complexity.
