Pre-Equalized MIMO Transmission Over Analog RoF Downlink in the Pres-Ence of Gain Imbalance
In this article, we propose a pre-equalization method in a wired-wireless multiple-input and multiple-output (MIMO) transmission over an analog radio-on-fiber (A-RoF) network. The MIMO transmission based on A-RoF suffers from un-flat and unbalanced response in the wired part, re-sulting in decreased channel capacity. A partial pre-equalization technique for wired part is compared to the one for the joint channels of wired-and-wireless by using 2 x 2 transmission of orthogonal frequency division multiplexing (OFDM) in a 5-GHz band testbed.
