In this report, an image components transmission scheme for the improvement of multipath delay resolution in a Fractional Sampling (FS) OFDM receiver is proposed.
FS is proposed as a diversity scheme and achieves path diversity by enlarging the bandwidth of the baseband filters in order to transmit the image components of the desired signal.
However, FS is not able to achieve diversity in case of multipaths with very short delays, because of its low multipath resolution.
Wider bandwidth of the transmission signal is required to improve the resolution of the delay.
However it is inefficient to occupy the large bandwidth with the imaging components.
To resolve the small delay multipaths, this paper investigate the FS path diversity with the imaging components on the separated frequency channel.
Numerical results through computer simulation show that the proposed scheme improves the multipath resolution and the bit error rate (BER) performance under the existing small delay multipaths. |
