APPARATUS AND METHODS FOR SYNCHRONIZATION OF TRANSMITTERS

A first-transceiver system for use in an antenna diversity scheme. The first-transceiver system comprising: a first-receiver; a first-time/clock-generation-unit; a first-transmitter; and a timing-controller. The first-receiver is configured to receive a wireless first-common-signal from a third-party-transmitter, wherein the first-common-signal is representative of a common-signal transmitted by the third-party-transmitter. The timing-controller is configured to: receive signalling representative of the first-common-signal; receive signalling representative of a wireless second-common-signal as received at a second-transceiver, the wireless second-common-signal being representative of the common-signal; and generate a timing-signal based on the first-common-signal and the second-common-signal. The first-transceiver system is configured to set the first-time/clock-generation-unit, based on the timing-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signai, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme that comprises aligned transmission of both the first-transmission-signal and a second-transmission-signal.
