Reducing multicarrier transmission peak power with a modified simple block code

A modified version of the simple block code (SBC) presented by S. Fragicomo et al. (see Electronics Letters, vol.34, no.10, p.953-4, 1998) is proposed to reduce the peak-to-average power ratio (PAPR) of multicarrier systems (such as orthogonal frequency division multiplexing). Combined with the sub-block processing technique (see Zhang, Y. et al., IEEE 49th Vehicular Technology Conference, vol.1, p.695-9, 1999), the proposed scheme can effectively reduce the PAPR of multicarrier systems with large frame sizes. For any given code rate, R⩾3/4, the maximum PAPR reduction that could be achieved by this kind of coding scheme is also derived. A binary phase-shift-keying (BPSK) multicarrier system model is assumed to compare with some well-known results
