The feedforward equalizer is used to minimize the error from channel and hardware imperfections.
In practice, the power amplification procedure at the transmitter end will inevitably introduce the nonlinear distortion due to hardware imperfections.
However, most of these studies are based on theoretical models and simulation analysis of assumed hardware imperfections without experimental verification.
It is the product of both the transmitter and receiver hardware imperfections (e.g., of their RF filters).
Distortions in modern communication systems arise due to hardware imperfections or inherent properties of the channel, e.g., fading.

Furthermore, the relative significance of each hardware imperfection (or combinations thereof) depends on the device characteristics and the specific system implementation and configuration.
Moreover, there are also various arising challenges to resolve such as the channel estimation and pilot contamination issues [86, 91, 92, 94, 95], suitable multi-cell coordination [90, 96], and hardware imperfection [97] to name a few.
Nonetheless, parallel transmission with accelerated pulses can be severely impeded by hardware and/or system imperfections.
However, in order to limit the Multiple Access Interference (MAI) from different users in a multicarrier based uplink due to imperfections in transmitter hardware, synchronization and Doppler spread, it is important to have some kind of power control to limit the difference in received power spectral density from different users.
In an IC, the difference between a defect and a fault can be explained as imperfections in the hardware and function, respectively.
