The present invention provides an apparatus and method for detecting the relative time of arrival of different signals at a single receiver from different respective transmitters, and causing the different respective transmitters to alter the time that they transmit their signals so that the time of arrival of signals from different transmitters is within a predetermined period. The present invention uses either a closed loop timing control, a GPS based timing control, or an open loop based timing control, to determine the time that signals from different transmitters need to be altered in order to obtain time of arrival for different signals within the predetermined period. As a result of the arriving signals being "semi-synchronous", any detection algorithms taking advantage of time synchronism, for example multi-user detection or interference rejection, can be much more effective in signal detection for the data transmitted from multiple transmitters to a single receiver.
