Abstract :
The exact probability density function (PDF) of the pre-scheduling signal-to-interference-plus-noise ratio (SINR) for per-user unitary rate control (PU2RC) systems is derived. A main contribution is proposing a novel dimension-reducing-type function to resolve the key problem, i.e. within a multi-dimensional complex space, to obtain the PDF of a unit isotropic vector´s maximum projection on vectors of an orthonormal basis. Even if PU2RC systems are only considered, the proposed function is quite useful for the analysis of other orthogonal beams-based MIMO systems as well. Monte Carlo simulations validate the analysis results.
