    Sammanfattning : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; relay networks; Multiple-input-multiple-output MIMO ; Cramer-Rao Lower Bound CRB .; least squares LS ;

    Sammanfattning : The use of intermediate-relaying nodes has been identified as a promising technique for enhancing coverage and combating the impairments of Multiple-Input-Multiple-Output (MIMO) wireless channels. The main ideais to introduce relays that forward the data to the destination which isotherwise out of the reach of the source. LÄS MER
