ABSTRACT:
Interference signal power in a TDMA communication system is determined by taking samples of a received signal. The TDMA system has a plurality of communication frequencies with sequences of frames communicated at each of the communication frequencies. Each of the frames contain a plurality of time slots, where each time slot is associated with a communication channel. The interference signal power is determined by receiving a signal at one of the plurality of communication frequencies. The signal is sampled for at least one frame period. The interference signal power is calculated using the M larger amplitude samples of the signal, where M is the number of samples that are taken during a period of time that corresponds to a length of one time slot.
