Abstract:

An experimental design approach is used to determine which factors design parameters of Spectrally Modulated, Spectrally Encoded SMSE waveforms have the greatest impact on coexistence with other communication waveforms. The SMSE framework supports cognition-based, software de- fined radio SDR applications and is well-suited for coexistence analysis. For initial proof-of-concept, a two factor parameter, three-level value experimental design technique is applied to a coexistent scenario to characterize SMSE waveform impact on Direct Sequence Spread Spectrum DSSS receiver performance. The experimental design methodology reliably captures factor level sensitivities and identifies those factors having greatest impact on system coexistence behavior bit error variation. Given these initial results and its effectiveness in other engineering fields, it is believed that experimental design may pave the way for developing more rigorous waveform design methods and allow more robust coexistence analysis of conventional, DSSS and SMSE waveforms.
