It is shown that cyclic\r\nshift and codeword inversion cause not change to peak envelope\r\npower. The encoding rule for the proposed code comprises of\r\nsearching for a seed codeword, shifting the register elements, and\r\ndetermining codeword inversion, eliminating the look-up table for\r\none-to-one correspondence between the source and the coded data.\r\nSimulation results show that OFDM systems with the proposed code\r\nalways have the minimum PAPR.","references":"[1] EBU, Digital Video Broadcasting: Framing Structure, Channel Coding,\r\nand Modulation for Digital Terrestrial Television, Draft EN300744,\r\nV1.2.1, Geneva, Switzerland, Jan. 1999.\r\n[2] IEEE Std. 801.11a, Wireless LAN Medium Access Control (MAC) and\r\nPhysical Layer (PHY) Specifications: High-Speed Physical Layer in the\r\n5 GHz Band, Piscataway, New Jersey, Sep. 1999.\r\n[3] J.A.
