* Introducing high-performance coding techniques such as Turbo Coding and low density Parity Check (LDPC), enhancing security and NLOS performance

The acquisition strategy of the NLOS project office was very similar to that of many other systems in development during the late 1980s.

[n.sub.los] and [n.sub.nlos] are the path loss exponents in LOS and NLOS conditions, respectively, the value within the range from 1.6 to 1.8 in LOS environment and within the range from 4 to 6 in NLOS environment.

In Case 4, the room door is now closed; thus, all observation points are hidden by the door (NLOS).

However, the contrary behavior was found when the receiver was in NLoS with the transmitter.

From the above studies, it is found that the diffractions from the ship's top structures and the shadowing due to its huge metallic body are the two main propagation mechanisms for the NLoS maritime applications.

Similarly for rural LOS scenario, a strong LOS component was observable, giving rise to an increased opportunity compared with NLOS case.

In line with expected large scale deployments of small cell networks in the near future, NEC is providing all of the key technologies required for the backhaul of small cells: high capacity millimeter wave and microwave, non-line-of-sight (NLOS) radio, wavelength division multiplex (WDM) optical access, full IP routing, unified network management systems and complementary software tools for network planning and optimization.

Another challenge associated with the design of efficient WBSNs is the highly degraded performance of non-line-of-sight (NLOS) links.

The Data channel measurements processed in this work were collected during 2003- 2006 in the building of Mobile Communication Laboratory at Eurecom Institute (Sophia anti polis) [5], two were conventional laboratory building built during the 1990s.Measurements are performed at spatially different locations for both Line-Of Sight (LOS) and Non Line Of Sight (NLOS).

Signals are transmitted under the line-of-sight (LOS) and/or non LOS (NLOS) conditions in such environments.
