Nonorthogonal Multiple Access for Visible Light Communication IoT Networks

Algorithm 1. Entropy approximation method.

1 initialization: Set , ; set as the stopping parameter, choose ;

2 let , and compute a_i according to (11);

3 compute the entropy by solving Problem (10);

4 if , stop, and output ; otherwise, , and go to step 2.
