1. Efficient DPD Coefficient Extraction For Compensating Antenna Crosstalk And Mismatch Effects In Advanced Antenna System
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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
2. GNU Radio + USRP2 Implementation of a Single-Carrier Zero-Correlation-Zone CDMA System
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)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
3. PERFORMANCE ANALYSIS ON MODULATION TECHNIQUES OF W-CDMA IN MULTIPATH FADING CHANNEL
Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandlingSammanfattning : 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
4. Analysis and simulation of channel equalization in TDD-CDMA
Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandlingSammanfattning : 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
5. Cross-layer optimization protocols in Ad-hoc networks: analysis and practical implementation of transport and network layers
L3-uppsats, KTH/ReglerteknikSammanfattning : 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.
