                                             OFDM Systems

Orthogonal Frequency Division Multiplexing (OFDM) has become the modulation method of choice for
many fielded and developing wireless communication systems. These systems include including Digital
Audio Broadcasting (DAB), Digital Video Broadcasting (DVB), various Local Area Networks (LAN) based
communication systems such as 802.11a, 802.11g, 802.11n, the ultra-wide band 802.15, and wire-line
systems such as Asynchronous Digital Subscriber Line (ADSL), as well as various Multiple-Input, Multi-
ple-Output (MIMO) systems. OFDM has been selected as the modulation process for these diverse ap-
plications because of its high tolerance for induced distortion and for its very efficient use of bandwidth.
We will review the structure and performance parameters of standard OFDM signaling schemes including
modulation and demodulation, carrier, timing, and sampling clock synchronization, peak to average ratio
(PAR) system considerations and control techniques. We will also examine several alternate developing
OFDM based structures.

fred harris holds the CUBIC Signal Processing Chair of the Communication Systems and Signal Process-
ing Institute at San Diego State University where since 1967 he has taught courses in areas related to
Digital Signal Processing and Communication Systems. He has extensive practical experience in com-
munication systems, high performance modems, sonar and advanced radar systems and high perform-
ance laboratory instrumentation. He holds a number of patents on digital receiver and DSP technology
and lectures throughout the world on DSP applications. He consults for organizations requiring high per-
formance, cost effective DSP solutions. In 2003 he became a Fellow of the IEEE and was cited for contri-
butions of DSP to communications systems. He is well published, is the author of “Multirate Signal Proc-
essing for Communication Systems” published by Prentice-Hall and has contributed to a number of other
DSP and Communication text books. He was the 2003 Technical Chair of the Software Defined Radio
Conference. In 1990 and 1991 he was the Technical and then the General Chair of the Asilomar Confer-
ence on Signals, Systems, and Computers that meets annually in Pacific Grove, California. He was also
the Technical chair of the Wireless Personal Mobile Communications Conference in 2006. In his copious
spare time, he is the co-Editor in Chief of the Elsevier DSP Journal.

He is the traditional absent-minded professor and drives secretaries and editors to distraction by request-
ing lower case letters when spelling his name. He roams the world collecting old toys and slide-rules and
riding old railways.
