    Abstract

    A diversity scheme with Fractional Sampling (FS) in OFDM receivers has been investigated recently. FS path diversity makes use of the imaging components of the desired signal transmitted on the adjacent channel. In this paper nonorthogonal access over multiple channels with iterative interference cancellation (IIC) and FS is proposed. The proposed scheme transmits the imaging component non- orthogonally on the adjacent channel. In order to accommodate the imaging component, it is underlaid on the other desired signal. Through diversity with FS and IIC, non-orthogonal access on multiple channels is realized. Our propose scheme can accommodate nonorthogonal signals with limited diversity gains.
