With the rapid increasing of maritime activities,maritime wireless networks(MWNs)with high reliability,high energy efficiency,and low de-lay are required.However,the centralized network-ing with fixed resource scheduling is not suitable for MWNs due to the special environment.In this paper,we introduce the collaborative relay communication in distributed MWNs to improve the link reliability,and propose an orthogonal time-frequency resource block reservation based multiple access(RRMA)scheme for both one-hop direct link and two-hop collaborative re-lay link to reduce the interference.To further improve the network performance,we formulate an energy ef-ficiency(EE)maximization resource allocation prob-lem and solve it by an iterative algorithm based on the Dinkelbach method.Finally,numerical results are provided to investigate the proposed RRMA scheme and resource allocation algorithm,showing that the low outage probability and transmission delay can be attained by the proposed RRMA scheme.Moreover,the proposed resource allocation algorithm is capable of achieving high EE in distributed MWNs.

In this paper,we focus on the pilot-assisted transmission design for downlink URLLC over non-reciprocal channels,in which the multi-antenna con-troller sends mission-critical data signals to a single-antenna actuator.In this system,the prior knowledge of
A joint Doppler shift and channel estima-tion method for the millimeter-wave communication system of an unmanned aerial vehicle(UAV)equipped with a large-scale uniform linear antenna(ULA)array has been proposed.Since Doppler shift induces in-tercarrier in
The sub-6G band is too crowded to accom-modate higher data rate,while the millimeter wave(mmWave)bands have abundant spectrum resources and massive MIMO can provide high spectral and en-ergy efficiency.Therefore,the combination of the two,namely mmWave-MI
Non-orthogonal multiple access(NOMA)has been integrated in millimeter-wave(mmWave)Massive MIMO systems to further enhance the spec-trum efficiency,but NOMA has not been fully consid-ered in lens mmWave systems.The fusion of these two technologies requires
