Abstract :
We analyze the performance of distributed MIMO transmissions in wireless networks, under the assumption of a line-of-sight environment. This leads us to the study of a new class of random matrices which depend on a linear number of random variables. We characterize the number of their significant singular values and give an upper bound on the size of their largest singular value. This translates into estimates on the number of degrees of freedom for the MIMO transmission.
