  3. 2. Frequency Noise in Widely Tunable Lasers for Coherent Communication

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Gabriela Cristina Dascalu; [2013]
    Keywords : ;

    Abstract : The objectives of this thesis are to measure the frequency noise of a widely tunable semiconductor laser, determine the main causes for the frequency uctuations and investigate the requirements for laser frequency noise for mQAM modulation formats by means of simulations. The following theoretical aspects are covered: the derivation of the frequency noise spectrum and the detuned loading effect from the rate equations; the shape and the causes of the frequency noise power spectral density; the derivation of the linewidth spectrum from white and 1/f frequency noise; the functionality of the laser and feedback loop used for the measurements.

  4. 3. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Hassan Sajjad; Muhammad Jamil; [2012]
    Keywords : Signal Processing; Fading Channel; Multi-hop;

    Abstract : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.

  5. 4. Performance Evaluation of LTE Physical Layer Using SC-FDMA & OFDMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abdul Samad Shaikh; Khatri Chandan Kumar; [2011]
    Keywords : OFDMA; SC-FDMA; LTE; BER; PAPR;

    Abstract : Since past few decades different types of cellular networks were launched and went successful on the radio links such as WiMAX, that became very popular because of its high data rate (70Mbps) and support for providing wireless internet services over 50km distance. The UMTS Long Term Evolution (LTE) is an emerging technology in the evolution of 3G cellular services. READ MORE
