该技术采用串行干扰消除代替全零初始化来完成某时刻多条路径到达角(Arrival of Angle,AoA)、飞行时间(Time of Flight,ToF)以及多普勒频移(Doppler FrequencyShifts,DFS)的初始化,并且对传统频域空间交替广义期望最大化(Frequency Domain Space Alternating Generalized Ex-pectation-maximization,FD-SAGE)算法进行改进,弥补了传统算法收敛速度慢以及噪声影响等缺陷。 |
This technology uses serial interference cancellation instead of all-zero initialization to complete multiple paths initialization including Arrival of Angle (AoA), Time of Flight(ToF)and Doppler Frequency Shifts(DFS). And the Frequency Domain Space Alternating Generalized Expectation-maximization (FD-SAGE) algorithm is improved to make up for traditional algorithms shortcomings such as slow convergence speed and noise impact. |

除此之外,本文采用基于最小代价多路径网络的混合数据关联方法解决了在不同时刻具有不同路径数目时无法进行路径有效关联的问题,同时该方法将固定时间窗中的最优匹配作为某时刻的关联数据,避免了某次关联错误导致后续关联失败所造成的不可逆错误。 |
In addition, a hybrid data association method based on the least-cost multi-path network is used to solve the problem of unable to effectively associate paths when there are different numbers of paths at different times. Meanwhile, the method uses the optimal match in a fixed time window as the correlation data at a certain time, which reduces the irreversible error caused by a subsequent association failure caused by the association error. |
