Abstract
Background: Due to the openness of wireless fading channel, it is easy to be disturbed by other transmission signals and noises. Encryption and decryption can guarantee the security of signals, and Physical Layer Security (PLS) which uses the features of fading channels itself to ensure the security of signal transmission has also been widely concerned. In addition, considering the wide applications of κ-μ shadowed distribution model and the advantages of Multiple-Input Multiple- Output (MIMO) technology, the confidentiality over Single-Input Multiple-Output (SIMO) independent κ-μ shadowed model has been studied.
Objective: To introduce the factors affecting the confidentiality on SIMO independent κ-μ shadowed model.
Methods: Novel representations of the lower bound on SPSC and SOP are deduced over independent κ-μ shadowed model. The method of moment matching to deal with infinite series is adopted.
Results: Through theoretical simulation and statistical simulation, the validity of our analysis is verified. We also get the curves for SOP and SPSC when the parameters of the channel change.
Conclusion: Under the condition of larger P, large L , large μD , large mD and small kD can improve the secrecy performance on independent κ-μ shadowed network.
Keywords: Multi-antenna technology, generalized fading channel, moment matching method, SPSC, SOP, physical layer security.
