Abstract

In this paper, we introduce newly developed DSP HW and SW module which is applicable to DTV-OCR and for cancellation of the interference signal. In general, RF repeater has problems of system oscillation and signal quality degradation due to feedback interference signal coming from transmit antenna. In this paper, we demonstrate newly developed DSP HW and SW module for cancelling the interference signal by investigating the field data measured through a RF repeater. Also, the structure and signal processing method for non-regenerative repeater system based on the newly developed DSP HW and SW module is illustrated as well.
