Security at PHY layer

Classé dans : SAN techniques | 0

SAN’s consortium addressed the issues of security at PHY level caused at two scenarios: firstly an intelligent jammer that tries to interfere a legitimate receiver and secondly an eavesdropper that tries to decode a confidential signal. For the first scenario … Lire la suite­­

Device to Device Communications

Classé dans : SAN techniques | 0

SAN’s consortium investigated the impact of D2D communications on the capacity of a cellular network. Two metrics were considered: average link capacity for UL, DL and D2D communications, and coverage probability taking into account end-to-end signal-to-interference-and-noise ratio (SINR). Analytical models … Lire la suite­­

Full-duplex relay

Classé dans : SAN techniques | 0

MIMO feedback channels have been measured on full-duplex relay in order to model the self-interference signal. The MIMO feedback channels have been characterized over the transmission bandwidth on two antenna structures (i.e. 2 arrays of 2 patchs back-to-back and 3 … Lire la suite­­

JNCC

Classé dans : SAN techniques | 0

Several bit-interleaved network coding (NC) designs have been proposed and evaluated in this context, including different constructions of the bit-interleaver placed between channel and network codes, different structures of the NC graph (e.g. using binary or non-binary codes, possibly coupled … Lire la suite­­

D2D DISCOVERY

Classé dans : SAN Standardisation | 0

ProSe Direct Discovery is defined as the procedure used to discover other UE(s) in its proximity, using E-UTRA direct radio signals via PC5. In Release 12, discovery mechanisms were not the main focus for Public Safety and it was required … Lire la suite­­

D2D COMMUNICATIONS

Classé dans : SAN Standardisation | 0

Since the current PMR standards already include direct communication between devices, the introduction of the device-to-device (D2D) communication in the LTE standard was one of the main requirements from Public Safety organizations. To cope with the timescale of the Release … Lire la suite­­

D2D SYNCHRONIZATION

Classé dans : SAN Standardisation | 0

When the UEs are within coverage, the synchronization is derived from the downlink signals transmitted by the eNodeB. In LTE, these signals are the Primary and the Secondary Synchronization Signals (PSS and SSS). The UEs derived from these two signals … Lire la suite­­
