Patent ID: RE43871

Claim:
A method of detecting a transmission from a primary cellular transmitter, the primary cellular transmitter transmitting on at least one channel frequency and being located in the vicinity of one or more secondary cellular transmitters, the method comprising the steps of : receiving a first stream of transmission data having a first received signal frequency at a first reception location for a first period of time; identifying the first signal frequency of the first stream of transmission data; correlating comparing the first stream of transmission data against a signal template plurality of predetermined burst structures to identify a first FCCH burst frame , the predetermined burst structures comprising at least one burst structure that includes a plurality of fixed bits in succession that indicate a training sequence ; identifying first FCCH time data corresponding to the first FCCH burst frame; and comparing the first signal frequency of the first stream of transmission data and the first FCCH time data corresponding to the first FCCH burst frame to a reference file , the reference file comprising a plurality of reliable measurements and a transmission cell sector corresponding to where each reliable measurement was received; and to determine determining one or more probable transmission cells based on the comparison .
