Abstract
In this paper, we design new efficient and fast
orthogonal frequency division multiplexing (OFDM)
transceivers by introducing parametric discrete Fourier and
Hartley transforms. We experimentally show that, for a specific
value of the parameter and for various signal-to-noise ratios and
modulation schemes such as binary phase shift keying (BPSK),
quadratic PSK (QPSK), 16 quadratic amplitude modulation
(QAM) and 64QAM, the resulting OFDM transceivers based on
these transforms achieve performance in terms of bit error rate
similar to that of the existing OFDM transceivers. The
compatibility of the proposed OFDM modulators with the
conventional DFT-based OFDM demodulator is also
experimentally verified. In addition, compared to the existing
OFDM transceivers, we show that the computational complexity
of the proposed OFDM transceivers is significantly reduced.
