once a luxury, have now become a necessity. The wireless technology was first
developed for army utilisation. But later, because of the wide applications
it had, it became a global obligation. But, today, with the advent of internet,
the security of the wireless networks has been at a great stake. And also, the
new generation of wireless network demands higher data requirements which is
achieved by higher data bits per unit bandwidth because of a variety of multimedia
applications, cost efficiency, spectral efficiency and security. In this study
all of these challenging requirements are met by Orthogonal Frequency Division
Multiplexing (OFDM) along with steganography. It is an attractive and explorative
area for the next and future generation of wireless multimedia applications.
The major challenging issue in the design of an OFDM transceiver is its high
Peak-to-Average Power Ratio (PAPR). In this study, design of an OFDM system
adopting Partial Transmit Sequence (PTS) and Selected Mapping (SLM) techniques
were concentrated. We analyse the system performance for various values of subcarriers
and modulation schemes by computing Complementary Cumulative Distribution Function
(CCDF) and analysing the Bit Error Rate (BER). PAPR value is low as the number
of subcarriers has been increased. PTS outperforms SLM when complexity is considered
and SLM is preferred when the redundant bits in the information are high and
data embedding algorithm is included after modulation to ensure wireless security.]]>Al-Kebsi, I.I.M.,2008Amirtharajan, R., K. Thenmozhi and R.J.B. Balaguru,2010Amirtharajan, R. and J.B.B.
