In this paper, we propose a new scheme using (he 1" order Reed-Mullcr (wco de with variables 4, RM(I, 4) which improves rhe performance of IEEE 802.1 Ig wireless local mea network (WLAN) modem in terms of peak-lo-average power ralio (PAPR) and symbol error probabilily (SER). We show the equivalence between complemenlary code keying (CCK) codeword and coset of the I" order Reed-Muller code with variables 3, RM(I, 3). This proposed system shows beller performance than CCK in terms of PAPR ond SER. When the numbers of IFFTpoint is 64. we reduce PAPR by 9dB and gel a codinggain of 3dB alsymbol errorprobabilify of IO4. Since lhe syslem of RM(I, 4) can be implemented using the RM(I, 3). there is a liffle increase in complexily.
