Massive multiple‐input multiple‐output has been broadly accepted as one of the key candidate technologies for enabling next generation (5G) wireless network. To ensure system performance, an efficient frequency dependent precoding has to be in place to pre‐compensate the frequency selective channel response in real time. This Letter presents a compact scalable frequency dependent precoding approach and its area‐efficient field programmable gate arrays (FPGA) implementation. The proposed approach has been validated and well compared with other architectures both in the Matlab/Simulink and Xilinx FPGAs.
