Heterogenous network is currently under intensive discussion within 3GPP as an effective solution to improve network coverage and capacity for long term evolution (LTE)-Advanced system, which consists of a mix of high-power macro base stations and a diverse set of low-power nodes, i.e., pico, femto and relay nodes. In this paper, we will particularly focus on the mixed deployment of macro and pico...
Space network are now become a very important and necessary complementary to the ground networks, it will extend the terrestrial Internet networks to space. However, there are still many challenges exist before the space-ground integrated networks come true, and how to transport data reliably in space networks is the very difficult one among these challenges. TCP has been a robust and efficient transport...
In OFDMA cellular system, the inter-cell interference is main interference of the system, which greatly degrades the system performance. In the inter-cell interference mitigation scheme, interference cancellation based on IDMA is a potential technology, especially in full-loaded scenario. Although it can enhance the system performance, its well work needs many information such as MCS, which makes...
In the wireless networks, utilization of terminals distributed in space can significantly improve the performance of wireless communication systems. In this paper, we investigate two-hop non-regenerative coded cooperation system and propose a novel design of employing linear dispersion codes (LDC) at the source node and a linear processing matrix at the relays. The relay stations make use of the knowledge...
