An RTCE-assisted ARO transmission scheme: design & performance

The authors provide an outline of the theory of the technique followed by a description of experiments to verify the method. Next, the design of an ARQ-based transmission system incorporating zero-crossing RTCE is described and its performance discussed. Finally, the application of higher-order zero-crossing analysis to RTCE and demodulation is considered. The dynamic range of the method is somewhat limited, but the system can be adaptively adjusted to make more effective use of this range by altering the length of the blocks over which analysis is carried out.<>
