The contemporaneous wireless communication employs one of the conventional strategies of interleaving methodology. An interleaver can be expounded as a single input and single output coterminous state device. The essential liability of an interleaver is to assemble a long block code from memory convolution code. The vital taxonomy of interleaver is random interleaver which scrambles data of disparate users with diverse patterns and deterministic interleaver which can be specified as modified circular shifting interleaver. Again, it expounds on system quintessential which gives an apothegmatic introduction about OFDM-IDMA transmitter and receiver. All systems are simulated in Xilinx platform for comparison on hardware constraints utilizing eight users with data of eight-bit/chip. The efficient interleaver consumes minimum hardware and time constraints. A comparison is made which unveils modified circular shifting algorithm that utilizes less devices when compared to random interleaver.

In 4G mobile communication, high data rates are required for communication. It is mandatory to find techniques that increase spectral efficiency with the limited radio bandwidth spectrum. Multiple access schemes play a vital role in wireless communication. Amid all multiple access schemes, Orthogonal Frequency Division Multiplexing-Interleave Division Multiple Access (OFDM-IDMA) is a hybrid scheme which seems to be a promising one. In OFDM-IDMA system, users are alienated by distinct interleavers rather than spreading sequences as in Coded Division Multiple Access (CDMA) systems. In OFDM-IDMA, the IDMA eradicates the Multiple Access Interference (MAI) among users using an iterative chip-by-chip detection algorithm. At the same time, the multipath effects are resolved by the OFDM layer. As a consequence, OFDMIDMA is capable of achieving the desired Bit-Error-Rate (BER) performance with relatively low decoding complexity.

One of the ancient diversity reception techniques used in wireless communication is interleaving mechanism. Interleaving is a typical signal processing technique used in a variety of communication systems. An interleaver can be explained as a hardware device to facilitate symbols from a fixed sequence as the input and formulates the identical symbols at the output in a divergent temporal order. The conventional use for interleaving is to scatter sequences of bits in a bit stream so as to minimize the effect of burst errors introduced in transmission. An interleaver is usually understood to be a single input and single output finite state device.
