Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a signal detection method and system. Background technique [0002] With the rapid growth of mobile services, the wireless network load is increasing day by day, and GSM900, DCS1800, and EGSM frequency bands have been put into large-scale applications one after another. While the distance between the base stations of the cellular wireless network is continuously shrinking, the number of high-carrier configuration sites is also increasing rapidly, and the frequency reuse density is continuously increasing. At present, the GSM wireless network of China Mobile Group generally has problems such as excessive overlapping coverage, serious cross-region coverage, a sharp increase in the probability of co-adjacent channel interference, and a significant increase in the noise floor of the wireless network system. These problems lead to the deterioration of wireless signal qua...

Problems solved by technology

These problems lead to the deterioration of wireless signal quality, serious interference of levels 5 to 7, and significant decline in user perception

[0003] In the traditional method of analyzing interference and coverage of regular hexagonal cell clusters, the boundary and center point of the frame period and slot period are only roughly estimated, resulting in large errors in the measurement of various parameters in signal detection, and even many parameters It cannot be calculated, which greatly limits the scope and degree of existing signal detection. Therefore, the existing signal detection scheme can no longer meet the increasingly complex wireless network analysis requirements, and the conventional drive test based on the existing signal detection technology And frequency scanning test methods cannot accurately locate the specific interfered frequency points, the degree of interference, and the location of the interference source cell in the serving cell, which has become a key technical bottleneck for further fine-tuning the current wireless network
