Titolo:
LMMSE Estimation from Vandermonde Matrices with Random Entries
Abstract:
We study the performance of systems for signal parameters estimation,
which are based on the linear minimum mean square error (LMMSE)
filtering. Such an estimation technique is widely used in practical
scenarios, specifically wireless sensor networks and
multiple-input-multiple-output (MIMO) communications. We model the
estimation system through sums and products of random matrices,
involving a d-fold Vandermonde matrix (d>1) with entries uniformly
distributed on the complex unit circle. Then, we derive the mean square
error (MSE) of the estimated signal by resorting to asymptotic analysis
and by applying the $\eta$-transform operator. We describe how our
results can be exploited for the study of practical systems, and we show
the agreement existing between the asymptotic results derived through
our analysis and the simulation results obtained for small values of d.
Tutti gli interessati sono invitati a partecipare.
Cordiali saluti,
