1. 1. Visualization of digital modulation techniques

   University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Author : Mustafa Can Tas; Fatima AlKurdi; [2021]
   Keywords : ;

   Abstract : Digital communication has gone through much development in the past decade. The literature in this field has developed and improved as well, but the educational materials still lack illustrative descriptions. READ MORE

3. 2. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Sergio Steven Gutierrez; [2020]
   Keywords : QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

   Abstract : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. READ MORE

4. 3. Modeling, Implementation and Evaluation of IEEE 802.11ac in Enterprise Networks

   University essay from Lunds universitet/Högskoleingenjörsutbildning i datateknik

   Author : David Åkerman; André Jönsson; [2016]
   Keywords : ns-3; wlan; 802.11ac; simulations; enterprise; Technology and Engineering;

   Abstract : Simulation studies are today an important tool in the development of new networks. For this purpose the NS-3 network simulator can be used. The focus of this thesis work lies on 802.11ac, the latest version of the Wi-Fi standard. READ MORE

5. 4. Modulation Coding In A Radio Link And Data Transfer Application Using L2 VPN Ethernet Over MPLS In A Large Network

   University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Author : Dogan Varli; [2015]
   Keywords : Radio Link; Path Loss; GNS3; QAM; MPLS;

   Abstract : In this thesis work, the locations where we are unable to reach via fiber are considered for wireless transmission links. In the practical part of this thesis different modulation techniques and antenna sizes were analyzed  in order to provide the most efficient way of data transmission. READ MORE

6. 5. PERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKSPERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKS

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : CLEMENT RANJITH ANTHIKKAD & IRFAN AHMED BAIG; [2013]
   Keywords : Orthogonal Frequency Division Multiplexing OFDM ; Peak-to-Average Power Ratio PAPR ; Complementary Cumulative Distribution Function CCDF ; Partial Transmit Sequence PTS ; Tone Reservation TR .;

   Abstract : This paper presents a new hybrid PAPR reduction technique for the OFDM signal, which combines a multiple symbol representations method with a signal clipping method. The clipping method is a nonlinear PAPR reduction scheme, where the amplitude of the signal is limited to a given threshold. READ MORE
