Abstract :
In this paper, incoherent multiple-input multiple-output (MIMO) systems operating over multimode fiber are analyzed theoretically. In particular, investigated is the influence of selection of the RF carrier frequency and other system parameters on the value of SNR at the MIMO receiver. It is shown that the RF carrier frequency should be greater than the baseband (3 dB) frequency. Furthermore, it is proved that the MIMO channel SNR reduction is smaller if the mode groups used for communication between transmitter/receiver pairs are different.
