Before any of these analyses capabilities can be modeled, the simulations of bit error rate (BER) and frame error rate (FER) against signal-to-noise ratio (SNR) have been conducted, requiring parameters from several known coding types (low-density parity-check (LDPC), convolutional, etc.), signal modulations (binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), etc.), coding rates (1/2, 1/3, etc.), and frame sizes (1,280, 3,580, etc.). However, in order to extract useful information from the results of these simulations, a curve fitting technique has been applied to each resulting dataset to extend and extrapolate the curve fit of BER and FER down to 10–30 using MATLAB® Curve Fitting ToolboxTM (The MathWorks, Inc.). This is a necessary step because simulations of BER and FER were only performed to around 10–9 due to the extensive simulation time that would be required to obtain significant simulation results at the error levels desired. Furthermore, the fitted curve results were applied to a finer resolution for the SNR at 0.01-dB interval instead of the 0.05-dB interval limitation used in the simulation. All the possible combinations of the coding types, signal modulations, coding rates, frame sizes, and the extension of BER and FER curves would enable users to capture a wide range of link performances that directly relates to the addition of higher level networking data encapsulated in a frame. The curve fitting results also led to the modeling of the optical link error rate performance by solving for coding gain, FER_BER SNR delta, coded optical BER-SNR, and coded optical FER–SNR.Document ID20190026442Acquisition SourceGlenn Research CenterDocument TypeTechnical Memorandum (TM)AuthorsOng, Victor Christopher A.*(California State University Long Beach, CA, United States)*Welch, Bryan W.*(NASA Glenn Research Center Cleveland, OH, United States)*Date AcquiredJune 18, 2019Publication DateJune 1, 2019Subject CategoryCommunications And RadarReport/Patent NumberNASA/TM—2019-220070GRC-E-DAA-TN65558Funding Number(s)WBS: 613673.02.06.03Distribution LimitsPublicCopyrightPublic Use Permitted.Technical ReviewSingle ExpertKeywordsCommunication link analysisFrame error rateAvailable DownloadsNameType20190026442.pdfSTIcloud_downloadcontent_copyvisibilityRelated RecordsThere are no records associated with this record.visibility_offNo Preview Available
