We first explain the protocol for multiplexing transmission followed by the explanation of the protocol for analog network coded transmission.
It can be seen that the analog network coded transmission with ANCTB outperforms multiplexing transmission with SMTB, which shows the benefit of beamforming-based PLNC for non-regenerative multi-way relaying.

Multiplexing Transmission.
It is shown that analog network coded transmission outperforms multiplexing transmission.
Due to the nonconvexity of the optimisation problem, suboptimum but practical transceive beamforming are proposed, namely, ZF, MMSE, and MSNR for multiplexing transmission, and MF and SDR for analog network coded transmission.
Two transmission methods are proposed to be applied at the RS, namely, multiplexing transmission and analog network coded transmission.
Two transmission methods for the BC phases are proposed, namely, multiplexing transmission and analog network coded transmission.
Besides using frequency division multiplexed (FDM) analog transmission of multiple carriers, it is possible to use digital (binary or on/off) modulation of lasers, which means modulating the lasers with a time division multiplexed baseband digital signal.
Based on the concatenation of erbium doped fiber amplifiers (EDFA), these high-capacity transmission systems take benefit from the huge potential of the wavelength division multiplexing (WDM) technique enabling transmission of several wavelengths on a single optical fiber.
