An apparatus and method for efficiently transmittingreceiving a control channel in a mobile communication system simultaneously supporting a synchronous High-Rate Packet Data system and an Orthogonal Frequency Division Multiplexing system. A local positioning module is connected to the tool to collect raw data describing motion of the LPM and tool within the work space. Further, the at least one time delay device is operative to introduce a time delay between a signal at an output of the at least one time delay device relative to a signal at an input of the at least one time delay device.
