N2 - We propose a novel positioning-communication integrated signal, which superposes the configurable positioning signal on the communication one to achieve a sub-meter range measurement accuracy. Different from other positioning schemes, there are multi positioning signals on different sub-carriers for different positioning users. The powers and bandwidths of these positioning signals are controllable, which reduces the near-far effect, and improves the range measurement accuracy. Other major contributions are: we analyze the interference of the positioning signal to the communication one; we give the lower-bound and measurement accuracy of the range estimation in both flat and fading channels, and derive their simple expressions. The results show the interaction between the communication and positioning signals is limited, and it is feasible to use the proposed signal for high accuracy positioning. © 2012 IEEE.
