The direct data recovery (DDR) uses adaptive data decoding (ADD) to combine a conventional reversal of data coding made on a transmit side with a reversal of received signal distortions introduced by a transmission channel; wherein both such reversals are achieved by the same conversion of a sub-range parameter or a referencing subspace (corresponding to said received signal) into data transmitted originally, by applying an ADD step comparing said sub-range parameter or referencing subspace with its reference or reference frame and using a result of such comparison for addressing a Content Addressed Memory (CAM) outputting recovered data.
