In this paper, the authors discuss about a very promising technique for 3G/4G, IFDMA. The performance of IFDMA signal in terms of impact of PAPR and its power spectral density. The interleaved frequency division multiple accesses is based on multicarrier and single carrier modulation and compression, repetition and subsequent user dependent frequency shift of a modulated signal multiple access. It is enabled by assignment of overlapping but mutually orthogonal subcarrier to each other. In this paper, the authors generate a signal with interleaving and generate its logistic map and they discuss its power spectral density of ifdma signal and coded performance with different data rates.
