Intra-array pilot measurements are performed with an antenna array of a MIMO transceiver. The antenna array comprises N transceive antennas. The antenna array is partitioned into K groups of antennas, G, k=1, . . . , K, wherein K&#x2265;2, each group Gcomprising Nantennas, A, i=1, . . . , N, of the antenna array. For each k=1, . . . , K, Spilot measurements, M, s=1, . . . , S, are performed, wherein S&#x2265;1 and wherein each pilot measurement Mcomprises transmitting simultaneously by each antenna A, i=1, . . . , N, of the group Ga pilot signal Pand generating by each antenna A, i'=1, . . . , N, of the other groups, G, k&#x2032;&#x2260;k, a received signal Yby receiving the pilot signals Ptransmitted by the antennas A, i=1, . . . , N. The measurements can be performed in a mode for detecting whether current hardware impairment parameters are valid or in a mode for updating the hardware impairment parameters.
