In recent years, vehicle crashes have taken nearly 38,000 lives per year in the U.S., according to the National Highway Traffic Safety Administration (NHTSA). To improve the safety of the drivers, the Federal Communications Commission (FCC) has allocated the Dedicated Short Range Communications (DSRC) frequency spectrum, viz. 5.850-5.925 GHz band for vehicular communication. However, the limited bandwidth at the DSRC band provided an impetus to explore the millimeter-wave (mm-wave) spectrum that promises much higher data rates. Nevertheless, operating in the mm-wave spectrum comes with the expense of high path loss and attenuation due to rain.
To overcome the abovementioned problems, …

Emerging 5G and 6G based wireless communications systems largely rely on multiple-input-multiple-output (MIMO) systems to reduce inherently extensive path losses, facilitate high data rates, and high spatial diversity. Massive MIMO systems used in mmWave and sub-THz applications consists of hundreds perhaps thousands of antenna elements at base stations. Digital beamforming techniques provide the highest flexibility and better degrees of freedom for phased antenna arrays as compared to its analog and hybrid alternatives but has the highest hardware complexity.
Conventional digital beamformers at the receiver require a dedicated analog to digital converter (ADC) for every antenna element, leading to ADCs for …
