抄録

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 resolution hysteresis-based SNF-ADC. Simulation results clarify that the channel estimation accuracy is improved by using hysteresis-based SNF-ADC and bit error rate (BER) performance is improved compared to cases with only a comparator.
