  1. 1. IOT CONNECTIVITY WITH EDGE COMPUTING

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Maximilian Stiefel; [2018]
    Keywords : ;

    Abstract : Billions of Internet of Things (IoT) devices will be connected in the next decades. Most devices are for Massive Machine Type Communication (MMTC) applications. This requires the IoT infrastructure to be extremely efficient and scalable (like today’s Internet) to support more and more devices connected to the network over time. READ MORE

  3. 2. Practical Aspects of Reduced Complexity LDPC Decoding using Forced Convergence

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

    Author : Muhammad Umar Farooq; Maria Garcia Garcia; [2016]
    Keywords : LDPC; Forced Convergence; Decoding; OFDM; IEEE802.11; Technology and Engineering;

    Abstract : This thesis is an extension to the previous work done at Department of EIT in investigating the complexity reduction of LDPC decoding using the stochastic approximation method to improve the energy efficiency of energy-limited applica- tions, such as in mobile phones. The research carried out in this thesis investigates the complexity and conver- gence results of adaptive performance control algorithm (PCAA) that changes the forced convergence threshold in OMS LDPC FC decoding algorithm.

  4. 3. 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

  5. 4. Embedding data in an audio signal, using acoustic OFDM

    University essay from Kommunikationssystem

    Author : Shuai Wang; [2011]
    Keywords : acoustic; acoustic OFDM; power control; embed;

    Abstract : The OFDM technology has been extensively used in many radio communicationtechnologies. For example, OFDM is the core technology applied in WiFi, WiMAXand LTE. Its main advantages include high bandwidth utilization, strong noise im-munity and the capability to resist frequency selective fading. READ MORE

  6. 5. A study of closed loop space time block coding techniques for MIMO-OFDM

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Shabbar Ali Khan; [2006]
    Keywords : closed loop space time block coding;

    Abstract : In this dissertation, the STBC-OFDM technique is therefore investigated in order to improve the bit error rate performance of such wireless communication systems speci¯cally those using multiple transmitter and receiver antennas.An investigation is undertaken of STBC with two transmit and one receive antennas as proposed by Alamouti together with quasi-orthogonal STBC with four transmit and one receive antennas.
