Change subject: libosmogsm/l1sap.h: extend ph_rach_ind_param with lqual_cb ...................................................................... libosmogsm/l1sap.h: extend ph_rach_ind_param with lqual_cb The link quality, defined by C/I (Carrier-to-Interference) ratio, can be computed from the training sequence of each burst, where we can compare the "ideal" training sequence with the actual training sequence and then express that in cB (centiBels, dB * 10). By analogy with both RSSI and ToA, it can be used to filter out false-positive detections and ghost Access Bursts.
