As a promising technique, OFDM has been widely used in emerging
broadband communication systems, such as digital audio broadcasting
(DAB), high-definition television (HDTV), and wireless local area
network (IEEE 802.11a and HIPERLAN/2). However, as the OFDM signals
are the sum of signals with random amplitude and phase, they are
likely to have large PAPR that require a linear high-power-
amplifier (HPA) with an extremely high dynamic range which is
expensive and inefficient. Furthermore, any amplifier nonlinearity
causes intermodulation products resulting in unwanted out-of-band
power. A number of approaches have been proposed to deal with the
PAPR problem, including amongst others, clipping,
clipping-and-filtering (CF), coding, companding transform, active
constellation extension (ACE), selected mapping (SLM), and partial
transmit sequence (PTS). This book proposes an improvement in the
selected mapping technique. The resulting scheme can also be
applied to the multiple transmitting antenna cases. Further, it
compares the simulation results to the existing techniques namely
exponential companding transform, repeated clipping and filtering,
and adaptive active constellation extension.
