4. 16QAM uses a mix of amplitudes and phases to achieve 4 bits/Hz. In this example, there are three amplitudes and 12 phase shifts.
While QAM is enormously efficient of spectrum, it is more difficult to demodulate in the presence of noise, which is mostly random amplitude variations. Linear power amplification is also required. QAM is very widely used in cable TV, Wi-Fi wireless local-area networks (LANs), satellites, and cellular telephone systems to produce maximum data rate in limited bandwidths.

While Multiple Phase Shift Keying (M-PSK) is much more spectrally efficient, the greater the number of smaller phase shifts, the more difficult the signal is to demodulate in the presence of noise. The benefit of M-PSK is that the constant carrier amplitude means that more efficient nonlinear power amplification can be used.

An-Efficient-and-Robust-Addressing-Protocol.rar - Address assignment is a key challenge in ad hoc networks due to the lack of infrastructure. Autonomous addressing protocols require a distributed and self-managed mechanism to avoid address collisions in a dynamic network with fading channels, frequent partitions, and joining/leaving nodes. We propose and analyze a lightweight protocol that configures mobile ad hoc nodes based on a distributed address stored in filters that reduces the control load and makes the proposal robust to packet losses and network partitions. We evaluate the performance of our protocol, considering joining nodes, partition merging events, and network initialization. Simulation results show that our protocol resolves all the address collisions and also reduces the control traffic when compared to previously proposed protocols.,2014-10-09 18:15:21,下载1次
Importance-of-Coherence-Protocols-with.rar - As Internet and information technology have continued developing, the necessity for fast packet processing in computer networks has also grown in importance. All emerging network applications require deep packet classification as well as security-related processing and they should be run at line rates. Hence, network speed and the complexity of network applications will continue increasing and future network processors should simultaneously meet two requirements: high performance and high programmability. We will show that the performance of single processors will not be sufficient to support future demands. Instead, we will have to turn to multicore processors, which can exploit the parallelism in network workloads. In this paper, we focus on the cache coherence protocols which are central to the design of multicore-based network processors. We investigate the effects of two main categories of various cache coherence protocols with several network workloads on multicore processors.,2014-10-09 16:38:45,下载2次

xml-ree-pattern.rar - With XML becoming a ubiquitous language for data interoperability purposes in various domains, efficiently querying XML data is a critical issue. This has lead to the design of algebraic frameworks based on tree-shaped patterns akin to the tree-structured data model of XML. Tree patterns are graphic representations of queries over data trees. They are actually matched against an input data tree to answer a query. Since the turn of the 21st century, an astounding research effort has been focusing on tree pattern models and matching optimization (a primordial issue). This paper is a comprehensive survey of these topics, in which we outline and compare the various features of tree patterns. We also review and discuss the two main families of approaches for optimizing tree pattern matching, namely pattern tree minimization and holistic matching. We finally present actual tree pattern-based developments, to provide a global overview of this significant research topic.,2014-03-22 16:01:10,下载4次

consumers’ names. The scheme is efficient and flexible because
MCP-ABE allows a content provider to specify an access policy

only the users whose attributes satisfy the access policy can decrypt

Enabling-dynamic-data-and-mutual-trust.rar - Ad hoc networks are new paradigm of networks offering unrestricted mobility without any underlying infrastructure. ROUTING is one of the most basic networking functions in mobile ad hoc networks. In partitioned networks, same addresses can exist between partitioned networks. Therefore, when several partitioned networks or independent networks merge into one network, potential address conflicts must be resolved. The address conflicts are detected through a DAD (Duplicate Address Detection) procedure. In reference 1, authors introduced three schemes: PDAD-RREQ Never- Sent (RNS), PDAD-RREP-Without-RREQ (RwR), and PDAD-2RREPs-on-RREQ (2RoR). These schemes can detect conflicts of a set of nodes but not all the duplicates and with a higher scope of false positives. This paper presents an adaptive version of PDAD.

AML-Efficient-Approximate-Membership.rar - AML EFFICIENT APPROXIMATE MEMBERSHIP LOCALIZATION WITHIN A WEB-BASED JOIN FRAMEWORK ABSTRACT: In this paper, we propose a new type of Dictionary-based Entity Recognition Problem, named Approximate Membership Localization (AML). The popular Approximate Membership Extraction (AME) provides a full coverage to the true matched substrings from a given document, but many redundancies cause a low efficiency of the AME process and deteriorate the performance of real-world applications using the extracted substrings. The AML problem targets at locating non overlapped substrings which is a better approximation to the true matched substrings without generating overlapped redundancies. In order to perform AML efficiently, we propose the optimized algorithm P-Prune that prunes a large part of overlapped redundant matched substrings before generating them.,2013-12-15 16:45:53,下载4次
