    Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  2. 2. Out-of-band transfer with Android to configure pre-shared secrets into sensor nodes

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Johannes Nilsson; Jameel Habbosh; [2018]
    Nyckelord :performance-constrained sensor nodes; out-of-band communications; pre key-exchange problem; smartphone-based transmitter; Technology and Engineering;

    Sammanfattning : Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. LÄS MER

  3. 3. Offset-PLL based frequency up-conversion for low spurious transmission

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Anders Nilsson; [2003]
    Nyckelord :Electronics; Offset-PLL; low spurious; up-conversion; radio; transmitter; modulator; Elektronik;

    Sammanfattning : The goal of this final year project is to investigate various techniques to up-convert a baseband signal into radio frequency signals, and to investigate the practical problems encountered in an offset phase locked loop design by implementation. Phase locked loops are commonly used in radio transmitters and receivers to generate accurate RF signals from a low-frequency reference. LÄS MER
