Résumé:
In this paper, we propose a scheme that preserves
the advantages of WCP-COQAM while guaranteeing in the
complex orthogonality. Indeed, WCP-COQAM is based on block
processing and uses circular filtering in order to remove time
overheads. However, like FBMC/OQAM scheme, WCP-COQAM
suffers from the presence of intrinsic interference that prevents
some MIMO techniques such as Alamouti Coding. This intrinsic
interference results from the non-complex orthogonal property of
WCP-COQAM and FBMC/OQAM. In this work, we show that
circular filtering makes the transmultiplexer impulse response
circulant. Our proposed scheme, called COW-CFMC, exploits
this circularity to restore the complex orthogonality by precoding
the data symbols in each subcarrier. Thus, we show by simulation
that our proposed scheme can enable Alamouti coding in a
straigtforward manner.
