The down converter reduces the frequency of the
signals from the radio frequency (RF) of 8-12 GHz to the IF of 15-115 MHz. The IF signals
are easier to analyze and can be sampled by the analog to digital converters (ADC). These
hardware components were provided by our Lincoln Laboratory supervisors

When considering how many forms of jamming are more efficient than barrage jamming
(PCFICH jamming, for instance, provides a 27 dB jamming advantage), i
t is clear that LTE is highly vulnerable to adversarial jamming
-------------------------------------------------------------------------------
The Physical Control Format Indicator Channel (PCFICH) is used to send the UE information re-
garding where the PDCCH is located in the time-frequency lattice. Without successful decoding of this
information, the UE will not be able to decode the PDCCH. The PDCCH contains information about
the UE uplink and downlink resource allocation, which is vital for receiving LTE service. Although it is
possible to jam the PDCCH directly, we will first discuss jamming the PCFICH

1.2 Jamming Strategies
Jamming is the ability to interfere, distort, or prevent the signal transmission be-
fore it received by its desired receiver. There are different ways to place the jamming
signal within the spread spectrum bandwidth. In this section, the most effective and
commonly used strategies of jamming will be presented.
1.2.1 Barrage Noise Jammer
The jammer transmits bandlimited white Gaussian noise. It is usually assumed
that the jammer power spectrum covers exactly the same frequency range as the
spread spectrum signal. The effect of the barrage noise jammer on the spectrum is
to increase the Gaussian noise level at the output of the receiver down converter. If
the power of the jammer signal is PJ watts, and signal has a bandwidth of W Hz,
the single-sided power spectral density (PSD) of the jammer is NJ = PJ /W .
1.2.2 Partial Band Jammer
To jam a spread spectrum signal, it is typically more effective to transmit all
the available jamming power in a limited bandwidth. This is called a partial band
jammer. If the fraction of the spread spectrum signal bandwidth which is jammed
is denoted by q, the PSD of the partial band jammer is NJ = PJ /qW , where PJ is
the total jamming power and, qW is the limited bandwidth of the signal which is
jammed. The partial band jammer is particularly effective against frequency hopping
spread spectrum systems because the signal will hop in and out of the jamming band
and can be seriously degraded in the jamming band [32], [33].
1.2.3 Single Tone Jammer
The single tone jammer transmits an unmodulated carrier with power PJ some-
where in the spread spectrum signal bandwidth. The single tone jammer is easily to
generate and is rather effective against direct sequence spread spectrum systems. To
achieve the maximum effectiveness of this jammer, the jamming tone should be placed
at the center of the spread spectrum signal bandwidth. The single tone jammer is
less effective against frequency hopping, since the frequency hopping instantaneous
bandwidth is small and, for large processing gains the probability of any hop being
jammed is small [33].
1.2.4 Multiple Tone Jammer
A better tone jamming strategy against frequency hopping systems is to use
several tones instead of a single tone. However, the power of the single tone jammer
will be shared by these multiple jamming tones. The jammer selects a number of
tones so that the optimum degradation occurs when the spread spectrum signal hops
to a jamming tone frequency. The optimum number of tones is a function of the
received ratio of signal power to jammer power (PS /PJ ). Multiple tone jamming is
also effective against hybrid systems [33].
1.2.5 ON-OFF Jammer
The ON-OFF jammer (pulsed noise jammer) transmits a pulsed band limited
Gaussian noise signal whose power spectral density just covers the spread spectrum
system bandwidth W . The duty factor (the fraction of time during which the jammer
turns on) for the jammer is denoted by ρ. The received jammer power spectral density
is PJ /ρW . This pulsed technique can also be used for single tone, multiple tone and
partial band jammers.
1.2.6 Repeater Jammer
A repeater jammer receives the spread spectrum signal, distorts it in some well
defined manner, and retransmits the signal at high power. The spread spectrum
receiver then receives the distorted signal at high power and it will track and de-
modulate this distorted signal. However, there are two main issues that should be
considered for this jammer. Firstly, the repeater jammer must distort the spread spec-
trum signal or else the jammer will act as a power amplifier for the desired signal.
Secondly, receiving and transmitting simultaneously in the same band of frequencies
presents formidable practical problems for the jammer.
1.2.7 Smart Jammer
For the jammer to be most effective, the jamming signal must be adapted to the
spread spectrum system and to the actual received signal power. A jammer which
has knowledge of the type of signaling being used, which can accurately predict the
received signal power, and which can adapt to transmit the optimum jamming signal
is called a smart jammer. A smart jammer is usually assumed in all worst case
designs
