  1. 16. M-PSK and M-QAM Modulation/Demodulation of UWB Signal Using Six-Port Correlator

    University essay from Fysik och elektroteknik

    Author : Negar A. Sani; [2010]
    Keywords : Six-Port Correlator; Ultra Wideband; Wireless Communication; Modulation; Demodulation; M-QAM; M-PSK;

    Abstract : Nowadays high speed and high data rate communication are highly demanded. Consequently, wideband and high frequency transmitter and receivers should be designed. New transmitters and receivers should also have low power consumption, simple design and low manufacturing price in order to fulfill manufacturers’ requests for mass production. READ MORE

  3. 17. PERFORMANCE ANALYSIS ON MODULATION TECHNIQUES OF W-CDMA IN MULTIPATH FADING CHANNEL

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : AUN ALI TAHIR; FENG ZHAO; [2009]
    Keywords : Final Thesis as Part for Master program in Electrical Engineering with Emphasis on Telecommunication;

    Abstract : The transmission from base station to mobile or downlink transmission using M-ary Quadrature Amplitude modulation (QAM) and Quadrature phase shift keying (QPSK) modulation scheme are consider in W-CDMA system. We can analysis the performance of these modulation techniques when the system is subjected to AWGN and multipath Rayleigh fading are consider in the channel. READ MORE
