Abstract
A method is provided for creating an artificial a fast fading channel in a MIMO communication system. The method includes encoding a series of source data to generate a first plurality of encoded output signals and multiplying the first plurality of encoded output signals by a plurality of random complex numbers to generate a second plurality of encoded output signals, and transmitting the second plurality of encoded output signals via the corresponding plurality of antennas. The transmitted signals vary in time and frequency independent of the channel conditions.
