This paper presents a new databroadcasting technique for transmitting data using the Orthogonal Frequency Division Multiplexing modulation scheme, within the NTSC television signal. The data signal is inserted in the vestigial sideband of the video signal. The advantages of this implementation are that the shape of the data spectrum minimizes the degradation of the picture quality and increases the noise margin of the data signal. Two approaches are taken to evaluate the performance of this… CONTINUE READING
