Hardware optimized digital resamplers based on half-band filters

Current paper proposes the research of hardware optimized half-band filters exploitation as low-pass filters in a resampling scheme. Filters hardware optimization is implemented by the quantization algorithm, which allows to replace multipliers with the set of shift registers and adders. This approach provides reduction of a crystal area and power consumption. Also, current work proposes the research of the influence of hardware optimized filters difference from initial filters on the resampling scheme performance. In addition hardware complexity-reduced filters resources compared with the initial filters characteristics. The proposed method can provide acceptable error level (-60 dB) and reduce complexity up to 70%.
