The design for QAM modulator below is for a standard 16-QAM constellation. The general form of an M-ary signal can be defined as S(t) = sqrt((2*Emin)/Ts)*ai*cos(2πfot) + sqrt((2*Emin)/Ts)*bi*sin(2πfot) Here‚ Emin is the energy of the signal with lowest amplitude and ai and bi are pair of independent integers chosen according to the location of the particular signal point. Fo is the carrier frequency and Ts is the symbol period. Non-rectangular QAM constellations achieve marginally better bit-error

Chapter One This report is based on the survey on the opinion about FM revolution in Bangladesh. As our course requirement was to prepare a term paper based on survey so we have selected FM industry as our project area. FM industry has taken a different look in our country now-a-days with the launch of three private FM stations. So the recent craze or popularity of FM stations is a very contemporary issue and can be referred as FM revolution. Therefore‚ we decided to conduct a survey to find out

QAM and QPSK: Aim: Review of Quadrature Amplitude Modulator (QAM) in digital communication system‚ generation of Quadrature Phase Shift Keyed (QPSK or 4-PSK) signal and demodulation. Introduction: The QAM principle: The QAM modulator is of the type shown in Figure 1 below. The two paths to the adder are typically referred to as the ‘I’ (inphase)‚ and ‘Q’ (quadrature)‚ arms. Not shown in Figure 1 is any bandlimiting. In a practical situation this would be implemented either at message level

aid. The law required ships at sea to leave their radio on 24 hours a day and required federal licensing of all radio transmitter ( RADIO ACT OF 1912 ). Edwin Armstrong made an early radio used amplitude modulation ( AM )‚ which have static and poor sound quality for music. Frequency modulation ( FM ) had less static but better sound quality for music. The radio also saw a surge of use during the First World War. Both sides used the radio to relay messages to troops and top officials as well as people

Richard Powers’ “Modulation” is about a mysterious‚ unhackable music virus that is taking over and controlling the minds of the people it comes in contact with. Out of nowhere this virus comes about and starts to spread vigorously through cyberspace‚ eating up computer software systems around the world. Not only is this virus spreading to computer systems and to data bases‚ but it starts spreading through people’s minds. Toshi‚ Marta‚ Jan‚ and Mitchell are the main characters in this story and all

should use the correct tone and vocabulary and promote our national language through FM channels. Its effect on the society is great as people learn language and are greatly influenced from FM language. Introduction Background: FM or frequency modulation means the encoding of carrier waves‚ such as the sound wave or audio signals of a radio or TV stations‚ by the variation-modulating-of its frequency resulting in little or no static and high fidelity of original sound in reception. Since there has

Radio Analysis 1. Introduction Every day‚ many people tune in to radio news. In Britain alone‚ every week over 12 million listen to news bulletins from the British Broadcasting Corporation (BBC) on five radio networks. The language of the news media‚ especially of radio news‚ offers a number of areas which are worth researching and investigating. An investigation of the linguistic features of the language in radio news - similar to any other investigation - needs a definition of what is to be
