The Interleaved Frequency Division Multiple Ac-
cess (IFDMA) scheme is based on compression, repetition and
subsequent user dependent frequency shift of a modulated signal.
Multiple access is enabled by the assignment of overlapping but
mutually orthogonal subcarriers to each user. In this paper it
is shown that IFDMA can be regarded as unitary precoded
OFDMA with interleaved subcarriers. On the other hand,
IFDMA is shown to be a CDMA variant with frequency domain
orthogonal signature sequences and chip interleaving. Thus, it
combines the advantages of single and multi carrier transmission
such as low peak to average power ratio, orthogonality of the
signals of different users even for transmission over a time
dispersive channel and low complexity. Simulation results show
the good performance of coded IFDMA transmission over a
mobile radio channel for different data rates.
