  1. 11. Stand-alone Dual Sensing Single Pixel Camera in SWIR

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : Martin Oja; Sebastian Olsson; [2019]
    Keywords : Single Pixel Camera; SWIR; Compressive Sensing; Single Pixel Imaging; Image Reconstruction;

    Abstract : A Single pixel camera is just that, a camera that uses only a single pixel to take images. Though, it is a bit more to it than just a pixel. It requires several components which will be explained in the thesis. READ MORE

  3. 12. Efficient Estimation of Decaying Sinusoids with Application in NMR Spectroscopy

    University essay from Lunds universitet/Matematisk statistik

    Author : Martin Jälmby; [2018]
    Keywords : decaying sinusoids; semi-parametric methods; wideband dictionary; NMR spectroscopy; Mathematics and Statistics;

    Abstract : In this thesis, the Wideband Sparse Exponential Mode Analysis (WSEMA) estimator is introduced. It combines two recently developed techniques, the wideband dictionary and the Sparse Exponential Mode Analysis (SEMA) to make for an efficient estimator. READ MORE

  4. 13. A Linear, Wide-band, Low-Power Receiver for Narrowband- Internet of Things (NB-IoT)

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

    Author : Rohan Raghunath; Ghanashyam Ravindranath Prabhu; [2018]
    Keywords : NB-IoT; FTNC; Harmonic rejection; N-path filtering; RX Front End; Low power; Wide-band; Passive mixer; Current mode; Technology and Engineering;

    Abstract : Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. READ MORE

  5. 14. RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem

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

    Author : Kishore Khed; [2018]
    Keywords : Technology and Engineering;

    Abstract : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

  6. 15. Compressive Sensing: Single Pixel SWIR Imaging of Natural Scenes

    University essay from Linköpings universitet/Datorseende

    Author : Andreas Brorsson; [2018]
    Keywords : Compressed sensing; Compressive sensing; CS; Compressive imaging; compressed imaging; CI; SPC; Single pixel camera; single pixel imaging; SWIR; Short-wavelength infrared; IR; infrared; Natural Scenes; DMD; Digital micromirror device; FOI;

    Abstract : Photos captured in the shortwave infrared (SWIR) spectrum are interesting in military applications because they are independent of what time of day the pic- ture is captured because the sun, moon, stars and night glow illuminate the earth with short-wave infrared radiation constantly. A major problem with today’s SWIR cameras is that they are very expensive to produce and hence not broadly available either within the military or to civilians. READ MORE
