Decision feedback equalization in SC-FDMA [PDF]
, 2008 SC-FDMA (Single-Carrier Frequency Division Multiple Access) is employed in the 3GPP LTE (Long-Term Evolution) standard as the uplink transmission scheme. The SC-FDMA signal has a low PAPR.

Security middleware for IMS-WLAN interworking
Revista Facultad de Ingeniería Universidad de Antioquia, 2013 The 3GPP proposes security architecture for Interworking WLAN-3GPP. However, it presents inefficiencies in the authentication procedure, which bring a greater consumption of radio resources, processing on the devices and delayed authentication.

On the Security of 3GPP Networks [PDF]
, 2000 Later this year we shall see the release of the Third Generation Partnership Project (3GPP) specifications for WCDMA - the first third generation standard for mobile communications. This 3G system combines elements of both a radical departure and a timid evolution from the 2G system known as GSM. It is radically different from GSM in having a wide-band
