SPATIALLY RANDOMIZED PILOT SYMBOL TRANSMISSION METHOD, SYSTEM AND DEVICE FOR MIMO WIRELESS COMMUNICATIONS |
摘要 |
Compressive sampling is used to generate pilot symbols to be transmitted over an array of antennas in a MIMO wireless communications device. A pilot symbol is transmitted over the array of antennas according to a spatially randomized antenna transmission function that randomly changes across the array of antennas. The randomized antenna transmission function may randomly select/deselect antennas and/or randomly change amplitude and/or phase of the pilot symbol transmission. Channel estimates can be constructed at a receiver based on the spatially randomized pilot symbols that were transmitted. |
