Multicarrier code division multiple-access (MC-CDMA) system is a promising technique for high-speed communication system due to robustness against intersymbol interference (ISI) over multipath.
In our opinion, transmitter switching can provide flexibility and robustness to an energy harvesting communication system, especially when a transmitter is unable to send data or the energy harvested from the environment is insufficient for data transmission.
To highlight our method, we improve the robustness of ciphering in a secure communication system.
In general, there are several aspects one must consider in selection of a waveform for a communication system such as bandwidth efficiency, scalability, interoperability, implementation complexity and robustness to imperfections including non-linearity, phase noise.
In order to investigate the system robustness, we consider possible mismatches in the observation and communication phases, respectively.
Note that the transmitted masked data frame presented in Figure 12c shows the robustness security of the information data, in the proposed wireless communication system, by the additive hyperchaos masking principle.
Some simulated tests will be presented in the following to evaluate the robustness of the adopted beamforming technique and the overall proposed hands-free communication system.
Owning to the advantages of high spectral efficiency and robustness against channel fading, orthogonal frequency division multiplexing (OFDM) has been applied in modern communication system extensively such as WLAN, WiMAX, LTE, and DVB-T.
It is compatible with the current state-of-the-art OFDM-based communication system and multi-antenna technologies, while the option for pulse shape design enables radio coexistence and improved robustness to time-frequency distortions.
dictates the power consumption margin, while robustness with respect to gain and second-order distortion variations is less of a concern for our UWB communication system.
The emergency communication system was inoperable.
