- Abstract
- We propose a symbol-aided approach to nonlinear
distortion cancellation and data demodulation in self-heterodyne
direct conversion (SHDC) receivers for discrete Fourier
transform (DFT)-based orthogonal frequency division
multiplexing (OFDM) systems. In order to cancel the
intermodulation distortion generated at the square-law device
output in the receiver, the SHDC transmitter generates an
OFDM symbol followed by the next symbols having a phase
difference of 90 degree. By using this approach, quadrature
modulation can be supported with direct conversion. The
advantages of the proposed technique are demonstrated through
the computer simulation.
