ABSTRACT:
In a communication system, the intensity and/or signal-to-noise ratio of a radio frequency signal received from a distant station is detected and a series of copies of the same data is generated. To improve the transmission efficiency under favorable conditions while minimizing errors under unfavorable conditions, the number of such copies is rendered variable in accordance with the detected intensity and/or signal-to-noise ratio, so that under unfavorable conditions the same data block is repeated in a greater number to correct errors and under favorable conditions it is repeated in a smaller number of reduce the transmission time.
