The invention discloses a multipath signal simulation method, system, electronic equipment and storage medium. The method includes the following steps: Step 1: Modeling according to an actual scene, and determining the existence of a relationship between a transmitting end and a receiving end based on a ray tracing method. Potential communication paths, including line-of-sight paths, primary reflection paths, and multiple reflection paths; step 2, based on the influencing factors related to the potential communication path that affect the quality of the received signal, respectively calculate the i-th influencing factor of the a-th potential communication path. factor index; step 3, calculate the weight of the ith influencing factor according to the importance of each influencing factor; step 4, calculate the influence function of the a potential communication path based on the factor index and its weight; step 5, based on each potential communication path The influence function of , selects several dominant paths from all potential communication paths; in step 6, multipath signal simulation is performed on the communication between the transmitter and the receiver based on the dominant paths.
Description
technical field [0001] The invention relates to the field of wireless communication multipath effects, in particular to a multipath signal simulation method, system, electronic equipment and storage medium. Background technique [0002] In complex geographical environments such as cities and mountains, there may be many obstacles between the transmitter and the receiver, and multipath effects are common. The signals received by the receiver usually include line-of-sight signals and non-line-of-sight signals. The signal includes multiple reflections. The multipath effect will bring problems such as delay synchronization, signal attenuation, polarization change, and link instability. Therefore, it is very important to perform multipath modeling and simulation. [0003] In the prior art, there is a method of obtaining all the multipath paths of the transmitting end and the receiving end through ray tracing for multipath simulation, but due to the existence of signal loss, ther...
