Abstract:
1. A network element for a wireless communication system locatable to couple at least one base station to an antenna array comprising a plurality of antenna elements, wherein 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; logic for applying at least one complex digital signal to at least one transceiver of a transceiver circuit of the plurality of independent transceiver circuits to produce a radio frequency translated version of the at least one complex digital signal; at least two feedback paths arranged to provide feedback of a radio frequency translated version of at least one complex digital signal such that the at least one fed back complex digital signal facilitates a determination of latency mismatch error response between at least two transceiver signal paths; processing logic arranged to provide latency mismatch error determination and Determine a path having a greatest latency; and adjustment means comprising delay logic arranged to apply latency correction coefficients to the at least one fed back complex digital signal output to/from the at least one transceiver to normalize latency across a plurality of transceiver paths to the path having the greatest latency.
