  1. 1. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yan Bixing; [2023]
    Keywords : Fading channel; auto-regressive model; power allocation; uncrewed aerial vehicle networks; Fading kanal; auto-regressiv modell; krafttilldelning; obemannade flygfordonsnätverk;

    Abstract : Power allocation algorithms that determine how much power should be allocated to pilot and data symbols play an important role in addressing the trade-off between accurate channel estimation and high high spectral efficiency for data symbols in the presence of time-varying fading channels. Dealing with this trade-off is highly non-trivial when the channel changes or ages rapidly in time. READ MORE

  3. 2. Stigmatization and its overshadow on urban green spaces in Gottsunda : the study of a segregated suburban area where existing green spaces are fading away

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Mashiat Raisa; [2023]
    Keywords : Gottsunda; stigmatization; segregation; green spaces; marginalized; crime; whiteness; planning; redevelopment;

    Abstract : In this modern era, when we are living in a society surrounded by advanced science and technology on the one hand, stigmatization as a form of social injustice is very much evident and still increasing in the social landscape on the other hand. In this thesis, I investigate the ongoing trend of redevelopment and densification projects in the Swedish context, explicitly targeting the marginalized neighborhoods in a Million Program housing areas built after the post-war period.

  4. 3. Secrecy Capacity of Cooperative Transmission with Opportunistic Relaying Scheme

    University essay from

    Author : Dhathri Pravallika Pasumarthi; [2022]
    Keywords : Cooperative Transmission; Opportunistic Relaying; Decode-and-Forward; Outage Probability; Secrecy Capacity; Fading.;

    Abstract : The usage of wireless communication has increased over the past few years. Most wired communications are replaced by wireless communication for ease of use. Wireless communication transfers confidential information like personal information and credentials between two entities. READ MORE

  5. 4. Backscatter Communications for 6G

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

    Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
    Keywords : Technology and Engineering;

    Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

  6. 5. Room for residential solar PV?: Exploring the socio-technical system narratives and barriers of the residential solar PV diffusion in Thailand.

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Sawinee Galaputh; [2022]
    Keywords : Socio-technical systems; solar photovoltaics; adoption barriers; community solar; Earth and Environmental Sciences;

    Abstract : In working to reduce this increasingly intensified effect of climate change, one of the key strategies employed by different countries around the world is to reduce Green House Gas (GHG) emissions from the energy sector. As they are one of the biggest contributors, the strategies include the employment of different mitigation actions and fading away from the conventional fossil fuel source to a more renewable source of energy production.
