Method and apparatus for transmitting orthogonal pilot tones in a multi-antenna communication system |
| abstract |
Methods and apparatus are provided for transmitting pseudo-orthogonal pilot tones in a multi-antenna communication system. Data is generated in a multi-antenna communication system with N transmit antennas by generating several pilot tones for each of the N transmit antennas and transmitting data via each of the N transmit antennas. The pilot tones for each of the N transmit antennas are pseudo-orthogonal to each other. Pilot tones are typically embedded in the data. Data is received in a multi-antenna communication system having N transmit antennas by receiving data via each of the N transmit antennas, and the data is several pilots for each of the N transmit antennas. -The tones are included and the pilot tones for each of the N transmit antennas are quasi-orthogonal to each other. The pilot tones can be orthogonal in the frequency domain, time domain, spatial domain, or all of these. |
