“…It also results in spectrum and scheduling inefficiency when packet retransmission for some of the UEs has to be adapted. S-HSDPA without HARQ achieves a higher nominal average throughput of around 1600 kbps which is far superior to the highest FACH data rate of 384 kbps reported in [14]. V. CONCLUSIONS Link level performance of S-HSDPA in an IMR configuration was simulated.…”

“…Here, the Forward Access Channels (FACH) is utilized as the transport channel for MBMS. Andrikopoulos [14] describes the field trial performance in which a real time experimental setup was implemented for the MoDis project in Monaco. The link level performance of the Secondary Common Control Physical Channel (S-CCPCH) for packet MBMS transmission has also been reported in [15].…”

The high speed downlink packet access (HSDPA) system has been investigated for adaptation in the GEO satellite environment in order to achieve high packet user throughput and system efficiency. This paper discusses the performance of the so called satellite-HSDPA (S-HSDPA) system, where the impacts of the power amplifier non-linearity, space time transmit diversity (STTD) and multicode transmission, are examined. The S-HSDPA performance is obtained from simulations of a modified terrestrial HSDPA link simulator in a rich multipath urban environment with three intermediate module repeaters (IMR). The results indicate an appropriate choice of system parameters.

“…In Europe, the main expression of DMB via satellite is the SDMB (Satellite DMB) project that involves a hybrid terrestrial-satellite system featuring a unidirectional satellite component [7]. The system definition and development have been largely pursued within the context of EU (European Union) and ESA (European Space Agency) projects [8,9]. As with DVB-H, SDMB relies on terrestrial mobile cellular networks for user interactivity, although limited capacity is also provided for particular types of point-to-point communications via satellite, e.g.…”

SUMMARYOne key aspect of digital multimedia broadcasting is the reliable point-to-multipoint distribution of content. Since the capacity and energy constraints in wireless environments do not favour the provision of a return channel for user feedback, the use of partial reliability techniques is often the only realistic option for the reliable transport layer design. In this paper, we focus on the two main reliable transport mechanisms in unidirectional, point-to-multipoint systems, namely packet-level forward error correction (FEC) and data carousels. We approach them as building components of an integrated scheme and investigate its performance via analytical means. Our analysis demonstrates that the network responsiveness, expressed by the average content access time, is optimized for certain packet-level FEC redundancy values. This is clearly different from setting FEC without considering the data carousel dimension, where the FEC redundancy is determined from the probability of recovering the whole file versus FEC overhead trade-off curves. We describe design alternatives for both scheme components, such as different FEC code types, rules for assigning FEC redundancy per carousel item, and ways to retrieve items from the data carousel, and evaluate their impact on the performance of the scheme. Our results suggest that the superposition of FEC on data carousels mitigates the otherwise significant impact of the data item retrieval technique on performance, at least for close-to-optimal FEC settings. On the contrary, the careful selection of FEC code and FEC redundancy assignment rule for data carousel items results in performance gains of up to 11 and 18% for the average content access time and FEC overhead, respectively, depending on the item demand and length distributions.

SUMMARYFuture mobile networks are expected to involve systems that are based on different technologies, such as WiFi, WiMAX, 2G/3G/3G1, LTE, and satellite. To address this scenario, ITU has defined integrated and hybrid networks in the framework of Next-Generation Networks. The interest is to exploit the cooperation of different wireless communication systems (segments) to provide service to mobile users in the most efficient way, taking into account signal quality (coverage), traffic congestion conditions, and cost issues. Integrated and hybrid networks have the potential to be an efficient and cost-effective solution to employ satellite communications for mobile users. In the view of this, our paper focuses on the design of integrated/hybrid systems taking into account physical, MAC, and network layers issues. System examples and standards are described as well. Then, cooperative diversity techniques and traffic engineering issues for overflow traffic are discussed. This paper concludes identifying some possible future trends.
