Abstract: A network element for a wireless communication system is locatable to couple at least one base station to an antenna array comprising a plurality of antenna elements. The network element comprises a plurality of independent transceiver circuits coupled to at least one of a plurality of respective antenna elements of the antenna array; and logic arranged to apply at least one complex digital signal to at least one transceiver signal path of a transceiver circuit of the plurality of independent transceiver circuits. A feedback path is arranged to provide feedback of the at least one complex digital signal such that it is capable of facilitating determination of latency mismatch error response between at least two transceiver signal paths. Adjustment means comprises delay logic arranged to receive a complex digital signal and provide a modified representation of the received complex digital signal in response to the latency mismatch error response of the at least two transceiver signal path.
