Without the extra expenses of signal bandwidth and transmitter power, Multiple Input Multiple Output(MIMO)technology can suppress the channel fading and noise utilizing multiple antennas at both the sender and the receiver. Taking advantage of MIMO technology, a so-called MIMO-DCSK chaotic communication scheme has been proposed and implemented based on Differential Chaos Shift Keying(DCSK). In view of this scheme, the present work is able to obtain the analytical Bit Error Rate(BER)expression through advanc...
