SAMMANFATTNING
This report is an introduction to orthogonal frequency-division multiplexing
(OFDM). The focus is on signal processing areas pursued by our research group
at Luleå University of Technology. We present an historical background
and some frequently used system models. Typical areas of applications are
also described, both wireless and wired. In addition to the general overview,
the addressed areas include synchronization, channel estimation and channel
coding. Both time and frequency synchronization are described, and the effects
of synchronization errors are presented. Different types of channel estimators
are described, where the focus is on low-complexity algorithms, and in this
context, advantages and disadvantages of coherent and differential modulation
are also discussed. Channel coding is described, both for wireless and wired
systems, and pointers are included to evaluation tools and bitloading algorithms.
An extensive bibliography is also included.
