Abstract :
In this letter, a spectral sidelobe-decaying property of the Walsh-Hadamard code employed in multicarrier code-division multiple access (MC-CDMA) systems is exploited. It is shown that the sidelobe-decaying characteristic of the MC-CDMA signal can be properly described by the code index of the underlined Walsh-Hadamard codeword.
