This guarantees that by using the power control strategies proposed in the next section, the outage probability QoS at the destination is satisfied.…”

“…The impacts of imperfect channel estimation in such networks have also been studied in [17], [18]. For an arbitrary but fixed number of Nakagami-distributed interferers per hop, authors in [15] derive closed-form expressions for the outage probability of AF and DF relaying. In [16], the authors have investigated the asymptotic error probability for the channel state information (CSI)-assisted amplify-and-forward multihop over Nakagami-m fading channels in the presence of the CCI.…”

Abstract-In this paper, we consider a decode-and-forward based wireless multihop network with a single source node, a single destination node, and N intermediate nodes. To increase the spectral efficiency and energy efficiency of the system, we propose a cooperative multihop communication protocol with spatial reuse, in which interference is treated as noise or can be canceled. The performance of spatial-reused space-time coded cooperative multihop network is analyzed over Rayleigh fading channels. In particular, the exact closed-form expression for the outage probability at the nth receiving node is derived when there are multiple interference sources over non-i.i.d. Rayleigh fading channels. Furthermore, the outage probability expressions are derived when nodes are equipped with more than one antenna. In addition, to reduce the effect of interference on multihop transmission, we propose a simple power control scheme which is only dependent on the statistical knowledge of channels. In the second approach for managing the interference, linear interference cancelation schemes are employed for both non-cooperative and cooperative spatial-reused multihop transmissions. Finally, the analytic results were confirmed by simulations. Simulation results show that the spatial-reused multihop transmission outperforms the interference-free multihop transmission in terms of energy efficiency in low and medium SNR scenarios.

“…The outage probability (OP) is a first-order statistical characteristic defined as the probability that the received signal-to-interference-plus-noise ratio (SINR) is below a specified threshold value. In [8,9], the OP was investigated in the presence of interferers for transmission over Nakagami-m fading channels, which has also been applied in cognitive and relay-aided systems subjected to interference-limited Nakagami-m fading channels [10][11][12][13]. Despite its benefits, the OP fails to provide holistic insights into the design of communication systems.…”

The performance of high-speed railway wireless communication systems is studied in the presence of co-channel interference and imperfect channel estimation in the uplink. The authors derive exact closed-form expressions for the outage probability and investigate the impact of fading severity. New explicit expressions are derived for both the level crossing rate and average outage duration for illustrating the impact of mobile speed and channel estimation errors on the achievable system performance. Our results are generalised and hence they subsume a range of previously reported results.
