As data rates increase, the sampling rate of ADCs also increases, leading to higher power consumption.
To address this issue, a reception method that reduces the sampling rate to the absolute minimum is being investigated.
In this reception method, the use of band-limited signals causes intersymbol interference (ISI), necessitating the design of an appropriate band-limiting filter.
Therefore, in this paper, we adopted an RC filter as the band-limiting filter, set the maximum frequency bandwidth as a constraint, evaluated the communication characteristics with respect to the roll-off coefficient α, and identified an appropriate value for α.
