The proposed architecture uses an improved optimization methods to obtain high speed system. To verify the efficiency of this system a DVB-T simulator in MATLAB matched with European Telecommunications Standards Institute (ETSI) is used to investigate the hardware design performance. The joint simulation of Xilinx ISE and MATLAB was performed including information framing, channel coding, and modulation. Also, a systematic design procedure based on FPGA for the proposed DVB-T system is presented and the results are reported. Hardware implementation results demonstrate the effectiveness of the proposed system and show that there is a good match between fixed-point implementations and floating-point simulations, while the high-throughput architecture is achieved in hardware implementation using the speed optimization methods in the design.

Research paper thumbnail of Reducing FFT Operations for FMCW Radars Range Detection

One major challenge with the digital signal processing (DSP) employed in FMCW radars is reducing the number of required computations in order to achieve a real-time operation. Most FMCW radars need to continuously perform the Fast Fourier Transform (FFT) to determine the object range, velocity, etc. This computational burden is a major obstacle to the radar real-time operation. In this letter, a computationally efficient FMCW radar is proposed capable of reducing the number of required FFT operations without sacrificing the resolution of the estimated range. With careful selection of parameters, simulations show that the new method can reduce the number of required FFT operations by a factor of about 119 and 183 in two different scenarios when compared to a conventional solution.

Research paper thumbnail of A low power and energy efficient 4:2 precise compressor based on novel 14T hybrid full adders in 10 nm wrap gate CNTFET technology

In this regard, this work aims to propose an energy efficient 4:2 precise compressor utilizing 10 nm wrap gate CNTFET technology. The proposed compressor is constructed from 2 hybrids 14-transistors full adders. The proposed Gate All Around (GAA) CNTFET based full adder employs a hybrid XOR/XNOR logic structure to lower the transistor count and power consumption. After performing rigorous simulations, we have demonstrated that the proposed GAA CNTFET based full adder and 4:2 compressor depict 175.3 nW and 308.5 nW power consumption respectively along with superior propagation delay response (4.4 ps and 10.57 ps respectively) at a 0.5 V nominal supply voltage. Moreover, the proposed designs occupy a lower layout area (0.195 μm2 and 0.43 μm2 for the proposed full adder and 4:2 compressor respectively) compared to the other counterparts. Our results accentuate the application of the proposed GAA CNTFET based 4:2 precise compressor for ultra miniature microprocessing systems.

Among these synchronisers, non-data-aided (NDA) or blind synchronisers are even more important due to bandwidth efficiency. In this study, a different approach is investigated to derive new feedforward NDA timing estimators based on Newton algorithm. Two novel estimators with four and two samples per symbol are presented and compared with traditional timing estimators, respectively. One of the main advantages of the second proposed estimator is the ability to control the loop gain automatically. This ability improves the convergence speed and robustness of the design. Simulation results show that the presented estimators outperform the conventional estimators over a noisy channel, especially at small excess bandwidth and low signal to noise ratio.

In order to simultaneously record of sEMG signals and the force produced by fingers, 9 requested movements of fingers conducted by 10 healthy people. Estimation was done for 6 degrees of freedom (DoF) and generalized regression neural network (GRNN) was selected for system training. The optimal parameters, including the length of the time windows, the parameters of the neural network, and the characteristics of the sEMG signal were calculated to improve the performance of the estimate. The performance was obtained based on R criterion. The Total value of R for 6 DoF was 92.8±5.2% that obtained by greedy looking system parameters in all the subjects. The result shows that proposed method can be significant in simultaneous myoelectric control.

In this study, a new method is introduced based on human visual system and saliency maps fusion to detect the small target in IR images with high reliability. By using the static and motion saliency maps fusion, emphasizing the obtained saliencies from one method to another and applying the information and benefits of all maps in the saliency map fusion, this method suppresses the background clutter and noise with high reliability, makes the target more prominent and finally increases the contrast among them. The experiments are carried out on some real-life data of IR images containing the moving target. The obtained results show the efficiency and robustness of the proposed method so that this method improves the target signal to the background noise and clutter and increases the contrast between them and also detects the small target in IR images with low false alarm rates and high reliability.
