Improved interference aware precoding for cellular network-mimo systems. García Fernández, J. J., Morales Céspedes, M., Sánchez Fernández, M., & Armada, A. G. In 2014 22nd European Signal Processing Conference (EUSIPCO), pages 1871-1874, Sep., 2014. Paper abstract bibtex An interference aware precoding scheme based on limited channel state information at the transmitter (CSIT) is considered for its use in the downlink of a cellular system. The transmitter precoder used is based on an MMSE-ZF criterion in order to maximize the user rate while the interference to other users is reduced. The proposed scheme also exploits the network topology, so that each BS can categorize the users into two groups, according to the level of interference that the BS is introducing in those users. On the receiver end, each user makes use of the whole channel state information at the receiver (CSIR) by employing an MMSE filter. This approach enables a reduction in the complexity of the system, while improving the performance of the whole network.
