Classification: CPC H | IPC H

Claim 19:
20. The transceiver of claim 11 wherein, in order to perform the gain measurements, GMTxiRxj, and the phase measurements, ϕMTxiRxj, for pairs of Tx and Rx antenna elements in the antenna array, the baseband processing system is further operable to, for each pair of Tx and Rx antenna elements Txi, Rxj:
transmit a pseudo random IQ signal of a desired bandwidth while the Tx antenna element Txi and the Rx antenna element Rxj are active;
cross-correlate the transmitted pseudo random IQ signal and a received IQ signal received via the Rx antenna element Rxi; and
compute the gain measurement, GMTxiRxj, and the phase measurement, ϕMTxiRxj, for the pairs of Tx and Rx antenna elements Txi, Rxj based on results of the cross-correlating.
