Apparatus, and an associated method, for facilitating communication of a data block communicated in an OFDM-based communication system. Side-informat ion required to be transmitted by many PAPR reduction schemes in OFDM is car ried and transmitted by sending orthogonal binary sequences superimposed on the OFDM data sequence carrying the information to be transmitted. In one em bodiment, a selected scrambling sequence is multiplied with an input data bl ock to yield a desired Peak-To-Average Power Ratio. An identification sequen ce one-to-one corresponding to the scrambling sequence is superimposed on th e resultant sequence and transmitted together. In the receiving station, the identification sequence is determined through correlation operations. This also determines the scrambling sequence. The effects of both sequences are f inally removed from the information-carrying data sequence.
