| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To develop small size base and relay nodes, it is desirable to improve power efficiency at power amplifier and reduce required hardware complexities at analog receiver circuits; analogto- digital (A/D) converter (ADC) and related analog hardware designs are important factors to simplify the transceiver circuits at each nodes. To mitigate the nonlinearity of a low resolution ADC for reducing the required analog hardware complexity, we have proposed two nonlinearity mitigation techniques are adopted, i.e., the dither ADC and the hysteresis ADC. In this paper, we investigate the effect of the linearity enhanced A/D conversion techniques on the achievable performance in single carrier modulation systems, where the dither ADC or the hysteresis ADC is adopted. Simulation results demonstrated that both the dither ADC and the hysteresis ADC are effective in improving BER performance of OQAM system and offset-QAM (OQAM) system affected by nonlinearity of ADC. |
