Abstract: A method of detecting a jamming transmitter includes the steps of indicating that a communication user equipment is capable of communicating in a cellular code division multiple access based radio network; testing a match of a uniform synchronization signal sequence of a synchronization channel; detecting a power indicator indicative of an unbiased wide band power of a received radio signal strength and comparing the power indicator to a noise floor threshold; and indicating a jamming affection of the communication user equipment in the case where (i) the communication indication is on hold; and (ii) the uniform synchronization sequence of the synchronization channel is not matched in the test, and (iii) the power indicator exceeds the noise floor threshold.
