Embodiment 1
[0034] An AP selection algorithm for a large-scale antenna system without a cell of the present invention will be described below with reference to the accompanying drawings and in combination with preferred embodiments of the present invention.
[0035] Step 1: For a non-cell large-scale antenna system with M APs and K users, the number M of APs is far greater than the number K of users. The number of orthogonal pilots in the system is T, and T
[0036] Step 2: Each AP judges the user type according to the distance from the user. Here, user types are classified according to the threshold Th1 and the threshold Th2. Such as figure 1 and 2 As shown, d(AP 1 ,UE 1 )≤Th1,d(AP 1 ,UE 2 )≤Th1, then the first user User1 and the second user User2 are the first API users. Th11 ,UE 3 )1 ,UE 4 )≥Th2 means that the fourth user User4 is a Class III user of the first AP.
[0037] Step 3: For the Type I users of AP1, User1 an...
