The probability based lock detection circuit determines whether a signal is sufficiently strong for communications in a mobile telecommunications system. If a signal is below a maximum energy threshold, the probability based lock detection is used to determine if the receiver is sufficiently capable to detect the signal and combine the signal with other signals received to obtain data transmitted by a mobile telephone. The probability based lock detection involves comparing index representations of maximums of 64 possible energies sent by the mobile telephone that identify that the signal was sent by mobile telephone. A mobile telephone sends signal that arrives to a base station through multiple paths to ensure accurate data transmission. Each signal includes data that identifies the mobile telephone. The probability based lock detection circuit determines whether the index of the maximum of 64 possible values of a signal sent to identify the mobile telephone is the same as the index of the maximum of the 64 possible values as calculated by combining all of signals sent by the mobile telephone.
