Özet

This paper presents optimizations for spectrogram matrix and signal detection processes which are used for signal sensing in software defined radio (SDR) applications. In industrial and literature applications, the software defined radio or software based receivers include field programmable gate array (FPGA) and digital signal processors (DSP) units for real time signal processing steps. In this study, it is performed real time signal sensing due to using CPU, providing four times speedup compared to multicore CPU which works at same platform. The other important result of our study is making SDR applications at real-time with mobile a computer instead of complex receiver architectures with high cost.
