Error Handling Method for Improving BDS Monitoring Accuracy of Bridge Deformation

Table 6

Error vector amplitude accuracy values obtained for the 16PSK-modulated signals before and after RLS-CMA equalisation.

16PSK SNR ratio/dB	0	4	8	12	16	20	24
Without equalisation	0.682	0.510	0.430	0.387	0.379	0.366	0.361
After RLS-CMA equalisation	0.476	0.473	0.383	0.304	0.229	0.167	0.144
Precision before and after equalisation	0.206	0.037	0.047	0.083	0.150	0.199	0.217
