Table 4 EE optimization with different number of users

Perform the following steps.

Initialization: system simulation parameters

  Step 1. Calculate the second step in Algorithm 1 to initialize the system environment.

 Step 2. Traverse the number of different cooperative SBS, N_CBS ∈ {0, 1, ..., C}.

Generate power constraints.

 Traverses the number of different Users equal to 10, ……, max{users} with users ∈ {10, 15..., 30}.

* Generate user fading channels under the current number of antennas N_current.

*Calculate the fading channel hunder the current user number

*Solve formula (13) using Centralized Algorithm——CMBF.

Step 3. Calculate E{R}, E {P_total}, EE
