FPGA Implementation of a Telecommunications Trainer System

Field programmable gate arrays (FPGAs) have been used in a wide range of applications including the field of telecommunications. This paper presents the use of FPGAs in the implementation of both analog and digital modulation that includes amplitude modulation, frequency modulation, phase modulation, pulse code modulation, pulse width modulation, pulse position modulation, pulse amplitude modulation, delta modulation, amplitude shift keying, frequency shift keying, phase shift keying, time division multiplexing and different encoding techniques like non-return-to-zero line code, non-return-to-zero mark line code, non-return to zero inversion line code, Unipolar return-to-zero line code, bipolar return-to-zero line code, alternate mark inversion line code, and Manchester line code. Moreover, an FPGA can be designed to emulate a particular device like an oscilloscope, a function generator, or the like. This paper describes the capability of an FPGA to internally generate a low frequency input signal and through the use of a VGA port, it is able to display the signals in an output device. However, the use of FPGAs is not limited to the aforementioned applications because of its reconfigurability and reprogrammability

A mobile disaster management system using the android technology

The Philippines is one of the countries in the world vulnerable to natural hazards because of its geographic location. It also lacks an efficient disaster management system that will help in times of need. One common scenario during disasters is that the activity of rescue and relief is not well-coordinated. For this reason, there is a need for a system that will help in the efficient provision of rescue and relief to disaster-affected areas. Since the use of smart phones is gaining interest in people, the disaster management system was implemented as a smart phone application using Google\u27s Android operating system. The disaster management system Android application known as MyDisasterDroid determines the optimum route along different geographical locations that the volunteers and rescuers need to take in order to serve the most number of people and provide maximum coverage of the area in the shortest possible time. Genetic algorithm was applied for optimization and different parameters were varied to determine the most optimum route

Tools and evaluation methods for discussion and presentation skills training

Our university is currently developing an advanced physical-digital learning environment that can train students to enhance their discussion and presentation skills. The environment guarantees an efficient discussion among users with state-of-the-art technologies such as touch panel discussion tables, digital posters, and an interactive wall-sized whiteboard. It includes a data mining system that efficiently records, summarizes, and annotates discussions held inside our facility. We also developed a digital poster authoring tool, a novel tool for creating interactive digital posters displayed using our digital poster presentation system. Evaluation results show the efficiency of using our facilities: the data mining system and the digital poster authoring tool. In addition, our physical-digital learning environment will be further enhanced with a vision system that will detect interactions with the digital poster presentation system and the different discussion tools enabling a more automated skill evaluation and discussion mining.info:eu-repo/semantics/publishe

FPGA-Based Digital Signal Processing Trainer

Field programmable gate arrays (FPGAs) have been used in a wide range of applications including the field of digital signal processing (DSP). This paper presents the use of an FPGA in the implementation of a DSP trainer that will serve as an educational tool to effectively teach the fundamental principles of digital signal processing. This trainer is capable of performing a 1024-point discrete Fourier transform, convolution, correlation, and finite impulse response filter, which includes a low pass, high pass, and band pass filter. This paper also describes the capability of an FPGA to internally generate different input signals like a square wave, triangle wave, and a sine wave, to accept an external signal from a microphone, an MP3 player and the like, to output the transformed signal in digital or analog form, and through the use of a VGA port, to visualize the signals in a display device making this trainer low cost

FPGA-based telecommunications trainer

The field programmable gate array (FPGA)-based telecommunications trainer serves as an educational tool to effectively teach the fundamental principles of telecommunication systems. It is capable of performing both digital and analog modulation, which includes amplitude modulation, frequency modulation, phase modulation, pulse code modulation, pulse width modulation, pulse position modulation, pulse amplitude modulation, delta modulation, amplitude shift keying, frequency shift keying, and phase shift keying. It is also capable of performing different encoding techniques, which includes non-return-to-zero line code, non-return-to-zero mark line code, non-return to zero inversion line code, Unipolar return-to-zero line code, bipolar return-to-zero line code, alternate mark inversion line code, and Manchester line code. All the mentioned modulation and encoding techniques have its demodulation and decoding counterparts respectively. Aside from modulation and encoding, this trainer is also capable of time division multiplexing. Because it was designed to be low-cost, this trainer does not need additional equipments like oscilloscopes and function generators. It is capable of internally generating a low-frequency input signal and using the VGA port to display its output. Moreover, since it is FPGA-based, this trainer can be reconfigured to perform other trainers (e.g. digital signal processing) making it open to a lot of possibilities
