Abstract:
1. A method comprising: at a multiple-input multiple-output (MIMO) communication device having a plurality of antennas and configured to send MIMO transmissions over a wireless channel, encoding a series of source data using a MIMO channel encoder to generate a plurality of encoded output signals; generating a plurality of pseudo-random complex numbers that are independent of conditions of the wireless channel and that are configured to vary over time faster than a channel characteristic of the wireless channel in order to produce an artificial fast fading wireless channel; multiplying corresponding ones of the plurality of encoded output signals by corresponding ones of the plurality of pseudo-random complex numbers to generate a plurality of transmit signals for transmission via a corresponding antenna of the plurality of antennas, wherein the plurality of pseudo-random complex numbers are configured to vary the amplitude and phase of the plurality of encoded output signals so as to form the artificial fast-fading wireless channel when transmitted via the plurality of antennas; and transmitting the plurality of transmit signals via the plurality of antennas.
