ISAC-Sim

Massive MIMO

Large-scale antenna array, 5G core technology

Real-World Applications

5G macro base stations. Using 64T64R (64 transmit 64 receive) or more antenna arrays. Sending data to dozens of users at different spatial positions at the same time and frequency (Space Division Multiple Access), increasing cell capacity by tens of times.

Experiment Steps

  1. Channel Hardening: Interference cancelled as N -> infinity
  2. Pilot Contamination: Inter-cell interference issue
