The case for the distributed method with equal distances between filled sub-carriers is defined as interleaved frequency division multiple access (IFDMA) [4].
Although, IFDMA PAPR is less than that of LFDMA, the LFDMA is used for practical application because subcarriers assignment with equidistance over the total bandwidth is very hard to be implemented, as IFDMA needs additional requirements such as guard-band between adjacent subcarriers and pilots [6].
