1. 1. Circular Modulation Formats and Carrier Phase Estimation for Coherent Optical Systems

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

   Author : Sebastian Joel Ortega Zafra; [2014]
   Keywords : ;

   Abstract : Digital coherent receivers stand today as a promising technology for the next generation of high-capacity optical systems. Coherent systems enable the use of multilevel modulation formats which increase the spectral efficiency of a system. READ MORE

3. 2. MIMO Channel Equalization and Symbol Detection using Multilayer Neural Network

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Athar Waseem; A.H.M Sadath Hossain; [2013]
   Keywords : MIMO; ISI; NN; SER; Channel Equalizer; QAM;

   Abstract : In recent years Multiple Input Multiple Output (MIMO) systems have been employed in wireless communication systems to reach the goals of high data rate. A MIMO use multiple antennas at both transmitting and receiving ends. These antennas communicate with each other on the same frequency band and help in linearly increasing the channel capacity.

4. 3. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Samiallah Shahid; Saqib Mohammad; [2013]
   Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

   Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE

5. 4. Automatic Modulation Recognition of Communication Signals.

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Muazzam Ali Khan; Yasir Ali Bangash; [2012]
   Keywords : Automatic Modulation Recognition; Neural Networks; Modulation Schemes.;

   Abstract : The project is aimed at designing an intelligent communication system where the receiver is able to detect the modulation scheme of the signal it receives using Automatic Modulation Recognition (AMR) algorithms, without having minimum or no prior knowledge of the transmitted signal. Six digital modulation schemes namely QPSK, BPSK, 2ASK, 4ASK, 2FSK, 4FSK and 16QAM were used. READ MORE

6. 5. 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
