Abstract
A base station includes an array of transceiver chains, each characterized by a bandwidth and including a transmit chain and a receive chain. The base station determines, at each center frequency and sub-bandwidth covering the bandwidth: a first set of interchain transmit gain and phase/delay differences across transmit chains; and a first set of interchain receive gain and phase/delay differences across the receive chains. The base station then determines, in a same manner as the first determining: a second set of inter-chain transmit differences; and a second set of inter-chain receive differences. The base station adjusts each transmit chain by the difference between the second set of inter-chain transmit differences and the first set of inter-chain transmit differences. The base station adjust each receive chain by the difference between the second set of inter-chain receive differences and the first set of inter-chain receive differences.
