One of the major disadvantages of Filter Bank Multicarrier (FBMC) is high Peak-to-Average Power Ratio (PAPR) of transmitted signal. As a result, nonlinear power amplifier (PA) properties, considerable out-of-band and the in-band distortion types take place in the case where the signals of high peak exceed the PA saturation level. In the present study, a new method of the PAPR reduction is presented and applied to reduce PAPR in FBMC/OQAM system. Different clipping methods have been proposed and studied that are Amplitude Clipping (AC), Palm Clipping (PC), Deep Clipping (DC), and smooth Clipping (SC) for the reduction of PAPR. To evaluate and analyze the performance of PAPR reduction methods, PAPR and Bit Error Rate (BER) measures are used and programmed using MATLAB program. The simulation results show that the clipping methods are strong substitute methods which may be assumed as a method of PAPR reduction for the FBMC-based communication systems and AC appears to be the best method.

Summary Wideband software‐defined radio (SDR) applications include data and time intensive operations such as wideband spectrum, signal detection, digital down conversion (DDC), and analog demodulation. Each of these processes need to be performed in order to produce the audio signal from the wideband signals. However, serial implementation of SDR applications do not provide necessary rate speed to obtain the sound and speech data in real time. In this work, we propose a real time SDR implementation using a heterogeneous architecture with CPUs and GPUs. To obtain the sound and speech data from the signals received and processed in SDR algorithms in real time, we also provide necessary optimizations. We test the proposed design using both single CPU core, multiple CPU cores, and GPUs. High performance is observed with our proposed algorithm in experimental tests. We also provide test results in a mobile setup where resources such as power and size are limited. For this purpose, we provide test results on NVIDIA Jetson GPUs and portable laptop CPUs. This work shows a proof of concept that the sound of a signal can be detected in the wideband spectrum and can be played back continuously in a real time with the help of the parallel programming suitable for low power consumption.
