Inter-cell interference is a major problem in multi-cell OFDMA systems and can severely degrade the system throughput, particularly for cell-edge users. An efficient technique to mitigate inter-cell interference (ICI), is interference coordination that allocates certain resources among users in different cells. In this paper, we propose a novel and distributed algorithm in order to mitigate the inter-cell...
In this paper, we consider the downlink of a cognitive radio network where a cognitive base station serves multiple cognitive users on the same frequency band as a group of primary transceivers. The cognitive base station uses an orthogonal scheduling scheme (TDMA/FDMA) to serve its users. For this purpose, the base station is interested in acquiring an estimate of the interference (from the primary...
Recently, several works have pointed out the negative impact of intercell interference variation on the performance of link adaptation in multi-cell single input single output (SISO) systems. However, the performance of adaptive precoder selection in multiple input multiple output (MIMO) cellular networks in the presence of interference variation is much less understood. In this paper we develop a...
