Does an empirical comparison between MMSE and sparse recovery methods for MIMO channel estimation exist?

MMSE and sparse recovery methods both aim at improving the classical LS channel estimation by injecting prior information. On the one hand, the prior information is learnt over time for MMSE (it...

In a MIMO system, how is an LMMSE channel estimator initialized in terms of covariance matrix?

In MIMO channel estimation, the linear minimum mean squares estimator (LMMSE) yields better performance than the least-squares (LS) estimator. However, it requires knowing the channel covariance...
