Outage Probability for Multi-Hop Full-Duplex Decode and Forward MIMO Relay
In this paper, a multi-hop (MH) decode-and-forward (DF) multiple-input
multiple-output (MIMO) relay network has been studied. To consider a more
realistic scenario, Full-Duplex (FD) operation with Relay Self-Interference
(RSI) is employed.
Assuming that the MIMO channels are subject to Rayleigh fading, a simple and
compact closed-form outage probability expression has been derived. The key
assumption to derive this result is that the mutual information of each channel
could be well approximated by a Gaussian random variable. In order to obtain
the resultant outage probability, a new excellent accurate approximation has
been obtained for the sum of Wishart distributed complex random matrices.
Numerical Monte Carlo simulations have been performed to validate our result.
These simulations have shown that, for low and medium interference regime, FD
mode performs better than Half-Duplex (HD) mode. On the other hand, when RSI
increases, HD mode can outperforms FD mode
