Robust simulation of waveforms

This paper presents a robust modeling and simulation method using a cost-effective worksheet program. The benefits of this approach are elaborated with some research work examples including secure adaptive waveforms, voice coding, modulation, channel and noise modeling. The performance of data communication over bandlimited channel systems is simulated with some robust worksheet models. Adaptive modulation methods are one of the forthcoming communication methods that are used in new military projects like joint tactical radio system (JTRS) designed according to new software communication architecture (SCA) standards. Physical level (OSI model layer 1) security aspects of the effective adaptive multi-carrier data transmission waveforms are future countermeasures against the increasing Internet or LAN intrusions. Band-limited frequency hopping is a promising secure wireless access method and should be used in telemedicine and other public or government data networks (wireless LANs). Robust worksheet modeling and simulation gives rapid answers to most important decision making problems without investments and learning process of complicated simulation packages. The robust worksheet simulation method, some examples of the results and physical level securing in modulation for biomedical and other secure data transmission purposes are described in this paper.
