Efficient Mobile Fronthaul Serving Massive MIMO New Radio Services Using Single-IF with Sample-Wise TDM for Reduced RRH Complexity and Ultra-Low Latency

Not Accessible

Your library or personal account may give you access


We firstly propose an efficient-mobile-fronthaul with single-intermediate-frequency and sample-wise TDM for new-radio massive MIMO applications. It is simple in architecture/DSP, spectral-efficient, and has low-latency/high-performance. Bi-directional new-radio/LTE-A mobile-fronthaul with 32×32 MIMO and 2-RRHs are experimentally demonstrated.
