question: What effect does increasing the antenna separation while keeping the number of antenna elements the same have on the correlation of the entries in the spatial channel matrix H? option 1: It makes the entries look more random and independent option 2: It makes the entries look more correlated option 3: It has no effect on the correlation of the entries in the spatial channel matrix H option 4: It improves the diversity of the channel option 5: It adds spurious basis vectors
