MPSoC programming is still a challenging task, where several aspects have to be taken into account to achieve a profitable parallel execution. Selecting a proper scheduling policy is an aspect that has a major impact on the performance. OpenMP is an example of a programming paradigm that allows to specify the scheduling policy on a per loop basis. However, choosing the best scheduling policy and the...
This paper applies combinatorial optimization techniques to improve the downlink transmission to multiple users in a network with cells, where intercell interference is a performance-limiting factor. A fair distribution of the signal-to-interference-plus-noise ratio (SINR) is desirable. A well-known technique to get a fair (balanced) SINR is max–min unicast beamforming (MBF). However, in a multicell...
This paper presents a new approach for a joint optimization of beamforming and temporal user scheduling for intercell interference mitigation in a multiuser multicell scenario using statistical channel knowledge. In general, the resource allocation problem considers two optimization criterions: fairness among the users in the network and a maximized sum rate of all users. The first one is achieved...
