1. 1. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
   Keywords : Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

   Abstract : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. READ MORE

3. 2. Modeling of DC-OFDM UWB physical layer in Matlab and design of demapping module with high diversity gain

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

   Author : Wenyan Su; [2011]
   Keywords : ;

   Abstract : Due to the development of semiconductor and digital communication technology, amounts of wireless communication technology have been presented recently. Among those techniques, Ultra Wide Band (UWB) technology is an outstanding short distance wireless communication technology. READ MORE

4. 3. Digital Power Detector for WCDMA Transmitter

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Robert Carlzén; Robert Nilsson; [2008]
   Keywords : Technology and Engineering;

   Abstract : A 3G mobile phone must have the ability to control its output power with high precision. A power detector is used to measure the actual power outputted by the power amplifier to the antenna. With higher data rates the traditional implementations with peak detectors have become very difficult to use, which is why true RMS detectors are needed. READ MORE

5. 4. Peak to Average Ratio Reduction in Wireless OFDM Communication Systems

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : KAMRAN HAIDER; [2006]
   Keywords : PAR; OFDM; Active-Set; Tone reservation; PSD constraint;

   Abstract : Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in today’s cellular systems. By going to higher bandwidth the (for low bandwidth) flat fading radio channel becomes frequency selective and time dispersive. READ MORE
