N2 - In this paper, we analyze orbital angular momentum (OAM)-based signal transmission over front-haul/back-haul links in beyond 5G networks where bit-interleaved low-density parity-check (LDPC) coded modulation is used. The back-haul/front-haul links are modeled by recently proposed two waves with diffuse power (TWDP) fading model. We evaluate bit error rate performance in detecting multidimensional LDPC-coded signals transmitted over a TWDP channel. By applying Monte Carlo simulations, we investigate the effects of constellation dimensionality, number of points in constellation and number of iterations in decoder on bit-error rate (BER) performance of an LDPC code for different channel conditions. For given channel conditions and a fixed number of points in the constellation diagram, the simulation results aim to illustrate performance improvement by increasing the order of constellation dimensions from 2 to 4.
