The third measurement campaign took place in Panagopoula tunnel, a 3.179 meters long tunnel located in Peloponnese-Greece. The setup of the measurement equipment was designed in a way that one can measure a more generic channel that is free of shadowing in T2I links. The channel sounder used could measure a 2×4 MIMO channel with a signal bandwidth of 25 MHz. The excitation signal was an OFDM-like transmitting signal with the subcarriers uniformly distributed in the measurement bandwidth and it was generated using Frank-Zadoff-Chu sequences. The signal was cyclically extended. The technique that was used for the MIMO measurement procedure is a popular fast switching method with a time division basic principle scheme that alternates between the transmitting antennas for each one of the receiving antennas.
