  1. 1. Efficient DPD Coefficient Extraction For Compensating Antenna Crosstalk And Mismatch Effects In Advanced Antenna System

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Himanshu Gaur; Md Zahidul Islam Shahin; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The demand for high data rates in a wireless communication system has experienced a remarkable growth over the last years. This demand is continually increasing with the growing number of wirelessly connected devices. Thus, there is a continuing hunt for increasing the data transmission rate in wireless communication systems. LÄS MER

  3. 2. GNU Radio + USRP2 Implementation of a Single-Carrier Zero-Correlation-Zone CDMA System

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Praveen Kumar Meenakshi Sundaram Gandhi; [2013]
    Nyckelord :;

    Sammanfattning : GNU Radio is a software defined radio in which components implemented in hardware are implemented using the software. GNU Radio works along with the USRP board. The USRP board is used to transmit and receive the signal in the wireless channel. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

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

    Sammanfattning : 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. LÄS MER

  5. 4. Analysis and simulation of channel equalization in TDD-CDMA

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :Muhammad Adnan Khan; Naseer-Ud-Din Shinwari; [2009]
    Nyckelord :CDMA; TDd-CDMA; Rake Receiver;

    Sammanfattning : The field of telecommunications has made tremendous progress of the past decade, especially in the area of wireless communications. The world becoming a global village due the advancement in the field of wireless communications, the requirement for standardization and uniformity becomes an essential issue. LÄS MER

  7. 5. Cross-layer optimization protocols in Ad-hoc networks: analysis and practical implementation of transport and network layers

    L3-uppsats, KTH/Reglerteknik

    Författare :Marco Belleschi; [2008]
    Nyckelord :;

    Sammanfattning : Ad-hoc wireless networks use multi-hop transmissions to communicate, without exploiting any infrastructure. Logical links create unreliable connections between nodes: the capacity of the channel can unpredictably change due to the presence of obstructions, interferences between nodes and stochastic phenomena such as fading.
