In this video, we demonstrate a simulation platform for hybrid beamforming in terahertz ultra-massive MIMO systems under practical hardware imperfections. The platform evaluates the impact of DAC/ADC quantization, phase noise, I/Q imbalance, phase shifter impairments, and power amplifier nonlinearity on system performance. Moreover, we evaluate our proposed compensation algorithms, which jointly model multiple hardware impairments and effectively mitigate their combined impact.
