Effect of Hysteresis-based Simple Negative Feedback A/D Conversion on Channel Estimation for Single Carrier Modulation
2020
IEICE Communications Express
In wireless communication systems, simplification of the receiver circuits is an important issue. In particular, an analog-to-digital converter (ADC) is one of the most important circuit blocks. To deal with this issue, a low-resolution ADC utilizing hysteresis-based simple negative feedback (SNF) technique (hysteresis-based SNF-ADC) was proposed to mitigate nonlinear distortion. In this article, we investigate a recursive channel estimation technique for single carrier modulation with one-bit
