    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Srinath Vasan; [2019]
    Keywords : SEM; AM; FM; DAB; SDR; SEM; AM; FM; DAB; SDR;

    Abstract : Hardware updates and feature updates of electronic equipment can take a long time for market implementations. Technology tends to become obsolete by the time the update is launched into the market. READ MORE

  3. 2. Design, Implementation and Comparison of Demodulation Methods in AM and FM

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Gaojun Chen; Sen Lin; [2012]
    Keywords : Demodulation; Envelope; Coherent; Square-law; FM to AM; Zero-crossing; Quadrature.;

    Abstract : Modulation and demodulation hold dominant positions in communication. Communication quality heavily relies on the performance of the detector. A simple and efficient detector can improve the communication quality and reduce the cost. READ MORE

  4. 3. Hybrid Color Halftoning

    University essay from Institutionen för teknik och naturvetenskap

    Author : Ahmed Tausif Aijazi; [2010]
    Keywords : Halftoning; Color; Hybrid; Flexography; Printing; image reproduction;

    Abstract : Halftoning methods can be divided into two main categories, namely AM (Amplitude Modulated) and FM (Frequency Modulated). Some printing methods, such as Flexography, are not able to produce dots small enough to handle the highlights and the shadows of the original image by just using AM halftoning method. READ MORE

  5. 4. Channel Estimation in GPRS based Communication System using Bayesian Demodulation.

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Dileep Kumar Appana; Chinni Anil Kumar; Nagappan Palaniappan Nagappan; [2009]
    Keywords : Bayesian; techniques; demodulation; demodulator; GPRS; rayleigh; fading; channel; dileep; appana; chinni; anil; nagappan; palaniappan; blekinge; tekniska; högskolan; institue; technology; master; thesis;

    Abstract : With the increase use of portable devices such as Personal Digital Assistants (PDA), laptops, voice and data integrated cell phones and many more, there is a need of wireless communication method using air as the medium to transmit and receive information between terminals. Radio waves propagate from transmitting antenna and travel through free space undergoing reflections, diffractions and scattering. READ MORE

  6. 5. DAB Transmission System Simulation

    University essay from Institutionen för systemteknik

    Author : Héctor Uhalte Bilbao; [2004]
    Keywords : Electronics; DAB; Terrestrial digital broadcasting; OFDM; COFDM; IFFT; FFT; SFN; SimulinkTM< sup>; Differential modulator.; Elektronik;

    Abstract : DAB (Digital Audio Broadcasting) is the radio digital system developed as an european standard by the ETSI, EN 300 400, based on the Eureka-147 group works, to improve the performance of the analogue radio systems (AM and FM). The system is based on the OFDM technology which allows DAB to exploit the spectrum frequencies in a better way with a higher quality of sound for mobile receivers specially. READ MORE
