Abstract :
This paper studies the performance of the vector channel probing method with feedback. The least squares (LS), minimum mean square error (MMSE), and a new scaled LS (SLS) approaches to the channel estimation are studied. Optimal choice of probing signals is investigated for each of these techniques.
