• Acronym: TDD-LTE like Massive MIMO
  • Short description: The massive MIMO physical layer platform allows a bi-directional OFDM communication with TDD-LTE specifications. The framework process 20MHz of signal bandwidth in real-time using FPGAs. Modulation, MIMO equalization, reciprocity calibration, linear precoding, among other features, can be adjusted to achieve different requirements.
