Paulraj, “Codebook-based lattice-reduction-aided precoding for limited-feedback coded MIMO systems,” IEEE Transactions on Commununications, vol. 60, no. 2, pp. 510-524, Feb. 2012. Abstract Lattice-reduction-aided precoding (LRP) provides near-capacity rates with the use of low-complexity linear receivers for coded multiple-input multiple-output (MIMO) systems. However, a large… Continue reading

Paulraj, “Opportunistic downlink interference alignment,” IEEE International Symposium on Information Theory (ISIT), June-July. 2014, pp. 1588-1592. Abstract We introduce an opportunistic downlink interference alignment (ODIA) for interference-limited cellular downlink, which intelligently combines user scheduling and downlink IA techniques. The proposed ODIA not only efﬁciently… Continue reading
