Fronthaul Optical Links Implemented by Using Sub-Nyquist Sampling Rate ADC for B5G/6G Sub-THz Ma-MIMO Beamforming

Not Accessible

Your library or personal account may give you access


We propose fronthaul link with 7-GHz IM-DD channels and 1/64 Nyquist-sampling-rate ADC to support 64 signals for 100-GHz Ma-MIMO beamforming. The corresponding CPRI-based capacity is 393.6374Gb/s. After fiber and wireless transmission, the EVMs are <8%.
