description | In this paper, we propose a parametric OFDM transceiver for wireless communication encryption.
One of the major contributions of this work is the intrinsic encryption nature of the proposed
system, since it is a completely new idea and philosophically different from the concept of existing
secured OFDM systems requiring separate encryption blocks. The main idea behind the proposed system
is the appropriate use of the parametric discrete Fourier transform (DFT-alpha) and its inverse
IDFT-alpha, where alpha is randomly obtained from [-2pi, 0], to implement the OFDM system and
at the same time inherently encrypt the communications. Thus, the resulting (IDFT-alpha/DFT-alpha)-based OFDM transceiver,
which has a performance similar to that of the conventional IDFT/DFT-based OFDM transceiver,
is applied and implemented in the IEEE 802.11a WIFI system framework OFDM for communication
encrypting. Moreover, using BER and SNR, we experimentally determine the appropriate intervals
of the possible values of alpha for perfect encryption in a flat fading channel assumed for optimal
testing environment. We also examine and assess the effects of DFT-alpha on the transformation of
the constellation pattern of the transmitted signal to prove the validity of the obtained intervals
for different modulation schemes such as BPSK, QPSK, 16QAM, and 64QAM. |
