提出了一种基于时分多址（IDMA）的全双工联合导航通信系统，该系统具有统一的信号结构。在发射机侧，导航数据和通信数据被线性叠加，并同时在相同的载波频率上发射。两种数据速率都可以在宽范围内调整，包括高数据速率。在接收器侧，导航数据可以几乎完美地与通信数据分离。该位置是通过信道估计器而不是延迟锁定环来估计的。不需要过采样。导航和通信在存在低信噪比、干扰和多路径的情况下是可行的，在这些情况下，传统的导航系统可能会失败。可能的应用包括但不限于室内场景。蒙特-卡罗仿真说明了导航和通信单元的性能。
In this paper, a full-duplex joint navigation and communication system with a unified signal structure based on interleave-division multiple access (IDMA) is proposed. At the transmitter side, the navigation data and the communication data are linearly superimposed and transmitted on the same carrier frequency at the same time. Both data rates are adjustable in a wide range, including high data rates. At the receiver side, the navigation data can be separated near perfectly from the communication data. The position is estimated by means of a channel estimator rather than a delay-locked loop. No oversampling is necessary. Navigation and communication is feasible in the presence of low signal-to-noise ratios, interference, and multipath – situations where conventional navigation systems may fail. Possible applications include, but are not restricted to, indoor scenarios. Monte-Carlo simulations illustrate the performance of the navigation and the communication unit.
