A lot of work has been done in the MU-MIMO BC to maximize sum rate (SR). Some of the solutions, especially the iterative ones, are capable of achieving very high performance. Nevertheless, they suffer from convergence problems. Closed form (CF) solutions on the other hand offer poor performances. This paper proposes a novel CF precoder design algorithm for the MU-MIMO BC, facilitated by stream selection...
We investigate in this paper the performance achieved by some SDMA (Space Division Multiple Access) access techniques in a Broadcast channel configuration. The study includes the two basic linear precoding schemes present in the literature namely the CF (Closed Form) and the Iterative precoding techniques. These techniques have already been widely studied for the i.i.d Rayleigh channel. In fact, these...
This paper proposes a new double iterative procedure for sum-rate maximization in a Multiuser MIMO system (MU-MIMO). The proposed algorithm is based on joint precoder and decoder optimization involving two different decoding schemes. For that we considered a precoding algorithm namely the iterative SJNR (Signal to Jamming and Noise Ratio) precoder combined with two iterative receivers. The first receiver...
This paper proposes a new iterative implementation algorithm for sum-rate maximization in a Multiuser MIMO system (MU-MIMO). The proposed algorithm is based on joint precoder and decoder optimization. For that we considered the best existing precoder design algorithm for a MISO multiuser system proposed in . This algorithm is based on the Lagrangian sum-rate maximization procedure. For the receiving...
