A method of detecting a jamming signal (304) in a wireless device (102)
includes providing a plurality of channels (401), wherein each of the plurality
of channels has an NCO frequency (428, 429), and receiving a channel lock
indicator (430, 431) for each of the plurality of channels. A jamming signal
is detected if the NCO frequency of each of the plurality of channels differs by
an integer multiple of an inverse of a pseudorandom noise code period (424,
425). A wireless device includes a plurality of channels, wherein each of the
plurality of channels has an NCO frequency. A frequency tracking loop for each
of the plurality of channels outputs a channel lock indicator for each of the plurality
of channels. A jamming detection module receives the channel lock indicator and
the NCO frequency from each of the plurality of channels. The jamming detection
module detects an interference condition if the NCO frequency of each of the plurality
of channels differs by an integer multiple of an inverse of a pseudorandom noise
code period.
