| Outline of Final Research Achievements |
This study shows that a 1-bit analog-to-digital converter (1-bit ADC) with the lowest resolution can receive signals beyond its resolution by utilizing noise. The main goal is to establish a fundamental theory of signal reception using a 1-bit ADC that exploits noise, building on the results of previous investigations into stochastic resonance phenomena. The target signal is the MIMO-OFDM signal used in fifth-generation mobile communications (5G). Through the development of receiver and reception experiments, the study demonstrates that even complex signals like MIMO-OFDM can be demodulated by a receiver using a 1-bit ADC that utilizes noise.
