  1. 1. Low Complexity Channel Estimation for OFDM Systems Based on LS and MMSE Estimators’

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Md. Jobayer Alam; Shaha Mohammed Goni Abed Sujan; [2010]
    Keywords : Channel Estimation; OFDM; LS Estimator; MMSE Estimator; SLS estimator; Complexity calculation;

    Abstract : 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.

  3. 2. Electrical and optical characteristics of InP interband nanowire infrared photodetectors

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Mohammed Amin; Md. Obaidul Alam; [2010]
    Keywords : ;

    Abstract : 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. READ MORE
