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.
