Original Abstract Submitted

the present invention describes a method, system, and a non-transitory computer readable storage medium to mitigate the side effects of imperfect channel estimation, analog processing imperfections, beamforming misalignment, and other imperfections present in massive mimo wireless communications systems. through the present invention, the user will have a better communication experience regarding data rate transmission, spectrum efficiency, and, specially, communication reliability. the core of the present invention relies on how the imperfections present in massive mimo systems are modeled and faced by adding more robustness to the proposed baseband precoder. in addition, the present invention has the capacity to be implemented in any hybrid hardware architecture, where the number of radiofrequency (rf) chains is lower than the number of antennas. this feature is crucial for massive mimo devices because having an expensive and energy-intensive rf chain per antenna would be impractical or even prohibit when the number of antennas is large.
