The precoded symbols,, are alternately transmitted to the two relays, allowing that each symbol reaches the UT through two independent links.
The initial probe is translated to the probe position of interest, and then is alternately transmitted and propagated through the sample.
The precoded symbols, s k, are alternately transmitted to the relays, allowing each symbol, when all paths are available, to reach the UT through L-independent links.
When one of the links fails, the bijectivity allows to recover the original symbols QPSK, as shown in Figure 4. Figure 4 Pairs of symbols alternately transmitted to each relay, according to a bijective function.

The two pulses are transmitted alternately by the same pulse repetition interval (PRI).
The MODEX-2 mode used in this experiment is a 3/4-aperture toggled-Tx configuration as depicted in Figure 1(c), where pulses are transmitted alternately with the first and the last three quarters of the aperture and the echoes are received simultaneously with two half subapertures.
