1. Low Complexity Channel Estimation for OFDM Systems Based on LS and MMSE Estimators’
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : In this paper we investigate the block-type pilot channel estimation for orthogonal frequency-division multiplexing (OFDM) systems. The estimation is based on the minimum mean square error (MMSE) estimator and the least square (LS) estimator. We derive the MMSE and LS estimators’ architecture and investigate their performances.

2. Electrical and optical characteristics of InP interband nanowire infrared photodetectors
Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)Sammanfattning : We have investigated two devices for detection of radiation, typically in the infrared range, Photons are absorbed in an active region of semiconductor devices such that the absorption induces inter band electronic transitions and generate photo-excited charge carriers. A photocurrent is generated between the conducting contacts through the active region of the devices. LÄS MER
3. An Exploration to Switching Barrier : Swedish Context
Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för managementSammanfattning : This thesis testifies the significance of switching barriers namely inertia, investment in relationship, switching costs, availability of alternatives and service recovery in the context of Swedish consumer. Though the barriers are proved as switching barriers it shows different trend in Swedish customers. LÄS MER
