All Communications Toolbox demodulator functions, System objects, and blocks can demodulate binary data using hard-decisions. Some of the demodulator functions, System objects, and blocks can also demodulate binary data using soft-decisions. The hard-decision demodulation computes the minimum Hamming dist...
ultrasonic transducers using digital modulations.Two types of transducers were tested based on PZT-5H ceramic based transducers and on PVDF polymers.The study includes MATLAB/Simulink simulations and experimental validations for BASK, OOK, BFSK and BPSK modulations with a 1MHz carrier at 125kbps baud...
The computational tool was developed using MATLAB® App Designer, a development environment that provides layout and code views, a fully integrated version of the MATLAB® editor, and a large set of interactive components [13]. This tool was created to compute and plot easily the optical spec...
Modeling of Digital Communication Systems UsingSIMULINK®introduces the reader to SIMULINK®, an extension of the widely-used MATLAB modeling tool, and the use of SIMULINK® in modeling and simulating digital communication systems, including wireless communication systems. Readers will learn to model...
system design6,7. Widening the bandwidth beyond these bounds is possible only by breaking one or more of the underlying assumptions on time invariance, passivity, and linearity3,4. Temporal modulations of antenna elements or the connected matching circuitry have been proven to be effective in this...

by using linear modulations to be used for hiding the high capacity of information. that means a steganography algorithm will be used to show the performance of the watermarking algorithms. also, this research focused on the robustness watermark embedded technique and capacity. in addition, the ...
While most mechanistic insights on the non-visual effects of light come from controlled laboratory studies with exposure to constant or parametric modulations of artificial light, there is now an emerging literature on the impact of “real-world” light exposure under ambulatory, daily life conditions...
The stimuli were defined by disparity modulations of fields of spatially bandpass dots. They were generated from an isotropic log-Gabor function with a spatial frequency of 0.5c/deg and a bandwidth of 2.4 octaves. They have the appearance of a central light blob with a darkened surround. Presen...
The dithering mechanism is analyzed using iADPLL simulation in Matlab. Due to the nonlinear effect of TDC, the overall performance of the dither mechanism is too complicated to analyze theoretically. It is important to evaluate the closed loop performance of the dither mechanisms with simulation. ...
