ABSTRACT:
In a TDM/TDMA digital radio communications system, time synchronization between fixed ports is achieved by adjusting the timing of a first port in response to the average timing difference between the timing of that first port and the timing measured by that first port of the downlink signals transmitted by a fixed number of the other ports in the system, which downlink signals are detected at the first port and determined to have the highest signal quality measures. Each of the other ports in the system sequentially performs the same process and the entire process is then reiterated a plurality of times at all of the ports until timing of the system converges.
