Abstract
A data acquisition system is disclosed where a first communication device transmits a transmitted signal to a second communication device. The second communication device encodes the transmitted signal with a code generating a retransmitted signal. The retransmitted signal is then transmitted back to the first communication device. The code can be indicative of an environmental element, such as a traffic sign. The first communication device can determine a distance to the environmental element by monitoring a time for the retransmitted signal to arrive. The first communication device can also encode the transmitted signal with information, such as voice for example.
