On the capacity of information-guided channel-hopping in multi-antenna system

In this paper, we deal with the capacity behavior of a new scheme, information-guided channel-hopping, which is proposed for high information rate communication over Rayleigh fading channel using multiple transmit antennas. This scheme is devised based on the fact that the independence character of the fading channels from multiple transmit antennas to the receiver can be used as an additional information transmitting channel, and the maximum likelihood decoding can be achieved in a simple way by decoupling of the signals conveyed by different methods. The analysis results prove that the capacity behavior of this scheme is better than that of the space-time block coding for the systems with more than two transmit antennas.
