Synchronization in coupled hyperchaotic oscillators is studied. Synchronization of hyperchaotic oscillators can be achieved using only one variable unidirectionalty coupled. The main advantage of this method is that it can be realized easily in engineer. The numerical studies and circuit experimental simulations show that this method is correct and efficient. In our circuit experimental simulations, the other variables of hyperchaotic systems synchronize precisely when a variable synchronizes generally.
