摘要
A partial spatial signature can be determined to be used in calibration. In one embodiment, determining the partial spatial signature includes receiving a first segment of a waveform, the first segment resulting from a radio transmitting a combined signal from a first antenna element, the combined signal comprising the sum of a first signal and a second signal, and calculating a first spatial signature related measurement using the received first segment, the first signal and the second signal. The process may further include receiving a second segment of the waveform, the second segment resulting from the radio transmitting the first signal from the first antenna element, and the radio simultaneously transmitting the second signal from a second antenna element, and calculating a second spatial signature related measurement using the second received segment, the first signal, and the second signal. Then, determining the partial spatial signature may be done using the first spatial signature related measurement and the second spatial signature related measurement.
