ABSTRACT:
A computational algorithm provides new and effective interference cancellation of the in-band spurious signals for the Orthogonal Frequency Division Multiplex (OFDM) transmitters. This new interference cancellation transmits non-zero tones may be used to cancel the interference generated by the modulated data signals. This minimizes the number of tones used and maximizes the interference suppression achieved at the same time. The technique described is one of active interference cancellation (AIC).
