- W4375854190 abstract "Authors research application of multi-frequency signals in modem based on soft-defined radio NI USRP-2920. Main goal of this work is to compare receiving multi-frequency signals as spectrally efficient frequency division multiplexing signals (SEFDM) in an experimental model using soft-defined radio (SDR) in addictive white Gaussian channel with modeling receiving. Spectrums of transmitted SEFDM signals with different factors of compressed bandwidth were shown. Signal constellations of SEFDM signals were demonstrated. Results show that energy gain of modeling in comparison with experimental model for factor of compressed bandwidth equal to 1 is 0.25 dB. For factor of compressed bandwidth equal to 0.9 energy gain is 1.5 dB. For lower factors values can not be measured. Differences between experimental BER and modeling BER is almost immeasurable while values of Signal/Noise Ratio (SNR) are low." @default.
