Abstract :
As multi-antenna being used in MIMO system to transmit signals with the same carrier frequency, one physical channel in MIMO will contain multi-virtual independent Rayleigh fading channels (VIRFC), among which very small relative time delay is existed, so the definition for the independent Rayleigh fading channel (IRFC) in MIMO theory is wrong. Also it is proved in the paper that joint receiver used in MIMO system could not transform these VIRFCs to IRSCs in the environment of MIMO system, so it is too difficult for MIMO system to be realized in CDMA mode or not.
