1. 1. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems

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

   Author : Hesham Sharkas; Haruhi Echigo; [2019]
   Keywords : 5G; Beamforming; Beam-forming; Beam Management; Beam Searching; Beam Sweeping; Codebook; code-book; Initial Access; MIMO; MillimeterWave; millimeter wave; mmWave; mm-Wave; mm Wave; Precoding; Slepian Beam; Synthesizer; Beam Synthesizer; Technology and Engineering;

   Abstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

3. 2. Turbo Decoder with early stopping criteria

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

   Author : Henrik Ljunger; [2016]
   Keywords : LTE Turbo Decoder Low Power Stopping Criteria; Technology and Engineering;

   Abstract : The turbo code used in the 3GPP Long Term Evolution(LTE) standard have been chosen specifically to simplify parallel turbo decoding and thus achieving higher throughputs. The higher data rates however leads to an increased computational complexity and thus a higher power and energy consumption of the decoder. READ MORE

4. 3. On-Chip Phase Measurement Design Study in 65nm CMOS Technology

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Daniyal Haider; [2015]
   Keywords : BIST; Vernier Oscillators; SAFF; Built-in-Jitter-Measurement; Timing Amplifier.;

   Abstract : Jitter is generally defined as a time deviation of the clock waveform from its desired position. The deviation which occurs can be on the leading or lagging side and it can be bounded (deterministic) or unbounded (random). Jitter is a critical specification in the digital system design. There are various techniques to measure the jitter. READ MORE

5. 4. A clock driver with reduced EMI

   University essay from Elektroniska komponenter; Tekniska högskolan

   Author : Mikael Bengtsson; [2014]
   Keywords : low-power; clock driver; low EMI;

   Abstract : A clock driver that works on the principle of charging and discharging the clock network in a VLSI circuit in two steps is investigated in a few different configurations. The aim of the design is twofold: to reduce the power consumption to reduce the third harmonic of the clock signal, and thereby the EMI (electromagnetic interference) emitted by the clock network.

6. 5. BERT and FFT measurement systems for high-speed communications and magnetometry

   University essay from Institutionen för teknikvetenskaper

   Author : Qiwei Zhu; [2011]
   Keywords : fpga; BERT; DSP; 8b10b;

   Abstract : This master thesis presents the development and implementation of two digital systems based on Field-programmable Gate Array (FPGA): a Bit Error Rate Testing (BERT) system for an Optical Communication (OCOM) application, and a Digital Signal Processing (DSP) system for a Spin-Dependent Tunneling Magnetometer (SDTM). Both applications are intended for space and currently under development at the Ångström Space Technology Center (ÅSTC). READ MORE
