Min-Max-MSE Transceiver Design for MU-MIMO VLC System

Algorithm 1

Iterative algorithm for joint design of precoders and equalizers.

(1) Initialize precoders within constraint (4) and set the DC bias . Let .

(2) Repeat:

(3)Update   with given according to (12);

(4)With  , solve problem (14a), (14b), and (14c) by using CVX to obtain the optimal precoders ;

(5).

(6) Until    or  , where is a predefined threshold and is the predefined default max iteration number.
