1. A method for embedding supplementary data channels in a communication system including a processor, the method comprising:
obtaining, by the processor, a primary data signal, the primary data signal including a given symbol, the given symbol including primary payload data prepended with a given cyclic prefix delineated into a first number of sequential prefix samples that are each of a sample-period duration; obtaining, by the processor, supplementary payload data; generating, by the processor, a modified primary data signal; and outputting, by the processor, the generated modified primary data signal for transmission via an air interface; wherein:
generating the modified primary data signal includes replacing, by the processor, an initial portion of the given cyclic prefix with a subset of the supplementary payload data delineated into a second number of sequential supplementary-data samples that are each of the sample-period duration, the second number being less than the first number; andreplacing the initial portion of the given cyclic prefix with the subset of the supplementary payload data includes replacing, by the processor, an initial second number of sequential prefix samples in the given cyclic prefix with the second number of sequential supplementary-data samples from the subset of the supplementary payload data. |
