Optimal A/D Conversion Considerations and Results
نویسنده
چکیده
Optimum scalar quantization is considered for the IIR filter and quantization system presented in "Power reduction in wireless receivers through multistage digital filtering and quantization" [1]. In [1], only suboptimum uniform quantization was used. An optimum scalar quantizer was constructed for a training sequence with a Signal to Interference ratio of −40dB, as was considered in extensively in [1]. While A/D distortion was lowered by 30%, solutions of comparable circuit power and complexity did not lower the overall bit−error rate.
