Abstract
A method for communication of plain information during channel access, according to a pre-defined channel access scheme, such as TDMA or FDMA or CDMA, by slightly modulating in a transmitter a parameter related to the channel access, such as time of transmission or frequency of transmission, using this modulation to encode plain information, while keeping the channel and the compatible receiver tolerant to this slight modulation.
