Abstract

We propose optical wireless multiple-input multiple-output (OMIMO) communications to achieve a high speed transmission with a compact transmitter and receiver. In OMIMO, by using zero forcing (ZF), we can eliminate the other signal interferences transmitted from other optical transmit antennas. Thus, we have no need to consider the frequency assignment for each optical transmit antenna. We analyze the signal-to-interference-plus-noise ratio (SINK) and the bit error rate (BER) of the proposed OMIMO with a linear array assignment of optical transmit and receive antennas, where we employ subcarrier multiplexing (SCM) for each optical transmit antenna. Note that the proposed OMIMO is applicable to other arrangements of optical transmit and receive antennas. We show that the proposed OMIMO system can realize MIMO multiplexing and achieve a higher speed transmission than one optical single-input single-output (OSISO) by setting the optical transmit and receive antennas and the transmitter semiangle appropriately.
