Abstract

We propose a matrix model for the interleaved orthogonal frequency division multiplexing system (IOFDM) [3], [4] [5]. Using this model, we show that the interleaving scheme originally proposed for IOFDM is not unique in terms of preserving system complexity. We further show that a class of interleaving matrices yields IOFDM systems with the same complexity as the original IOFDM system. Furthermore, we show that the interleaving scheme does not affect the BER performance of the system as long as the interleaving matrix is unitary.
