Gfdm based concatenated ldpc codes to improve the performance of usrp operated communication systems

Abstract

newline The number of connecting devices is rapidly increasing newlineworldwide in wireless communications, leading to increased data traffic. newlineSingle-channel coding schemes are not enough to detect and correct the newlinedata bits. So additional channels are required for future applications newlinesuch as broadband, emergency, and surveillance services. There is a newlineneed for novel channel coding schemes to handle significant data traffic. newlineSoftware-defined radio has the tuneable capability to deploy newlineradio communications in free space and supports applications in the newlinephysical layer. Generalized frequency division multiplexing (GFDM) is newlineone of the 5G candidate waveforms and has malleable pulse shaping newlinefilter flexibility. The concatenation of channel codes is proposed in this newlinethesis work on software-defined radio (SDR) hardware platform based newlineon the GFDM system to handle the enormous data traffic in the fifth newlinegeneration. newlineIn the first method, the single input single output (SISO) newlineconfiguration of the GFDM system model is designed mathematically newlineand virtual programmed with the USRP device configuration. The SDR newlinedevice generates the GFDM complex waveform transmitted into free newlinespace with Gaussian noise impairments. In the receiver, the
