Abstract

With the development of mobile Internet, the demand for location based service highly increased. The widely used GNSS has a weakness for indoor positioning, while the Pseudolites Positioning System on the ground can achieve seamless outdoor and indoor positioning. Most of the Pseudolites Positioning System use the spread spectrum navigation and positioning signal system like GNSS, whose signal is usually generated followed by information modulation, spread spectrum modulation and RF modulation. Due to the specificity of indoor positioning, the system have to generate multiple signals carrying different information. To implement the indoor covering of positioning signal, every single signal should be wired to the indoor antenna individually, which increased the difficulty and cost of indoor covering. To reduce the difficulty of construction and solve the positioning accuracy problem caused by the differences of cables, the paper presents a method based on the frequency division multiplexing. The method transmits only one channel signal which is composed of multiple positioning signals assigned a different carrier frequency to multicarrier signal processing module used for choosing the specific positioning signal transmitted by specific antenna. The simulation result shows that the method can transmit multiple positioning signals by one cable to multiple antennas, reduce the cost of construction and improve the positioning accuracy at the same time.
