Controlling Software Complexity: The Business Case for Static Source Code Analysis

Because of the increasing role software plays in almost every facet of our lives and businesses, developers are under constant pressure to perform. They are challenged to deliver increasingly advanced applications on stringent timetables. Compound this with the growing complexity of applications themselves, add distributed or outsourced development teams, and...

Complexity and false hope

It's hard to simplify complexity. Sometimes, this painful reality causes managers to grasp at straws and wallow in denial, seeking the allure of easy, yet ultimately pointless, solutions. The following Geek and Poke cartoon precisely captures this unfortunate, yet all too common, phenomenon: ...

Complexity sucks...Simplicity rocks

Want to skillfully avoid IT project failure? Then simplify. IT failures are often accompanied by a complex set of organizational, political, and technical dynamics. When conflicting agendas and lack of consensus arise out of this complexity, the project is at risk. In fact, unless this complexity is...

Ever Wonder Why Upgrades Are So Damn Hard?

It's no secret that every vendor needs its customers to upgrade early and often. While much of this requirement is centered around support costs – vendors have trouble banking all those big maintenance bucks they're earning if they have to support too many older versions of the software – long-term...

Reference Frame Optimization for Multiple-Path Video Streaming With Complexity Scaling

Recent video coding standards such as H.264 offer the flexibility to select reference frames during motion estimation for predicted frames. This paper studies the optimization problem of jointly selecting the best set of reference frames and their associated transport QoS levels in a multipath streaming setting. The application of traditional...

Bandwidth Efficient Channel Estimation Using Super-Imposed Pilots in OFDM Systems

This paper proposes a channel estimation algorithm using super-imposed pilots for OFDM systems. The pilot symbols are added linearly to the modulated data symbol at a fraction of the total transmit power, making the method spectrally efficient. This paper presents a series of iterative and non-iterative receivers in which complexity...

The Complexity of Connectivity in Wireless Networks

This paper defines and studies the scheduling complexity in wireless networks, which expresses the theoretically achievable efficiency of MAC layer protocols. Given a set of communication requests in arbitrary networks, the scheduling complexity describes the amount of time required to successfully schedule all requests. The most basic and important network...

Managing QoS Policies Means More Business

Whatever mix of technologies emerges from this era of converging voice and data services on IP networks, one thing is certain - tomorrow's IP networks will be more complicated than today's networks by orders of magnitude. That complexity has consequences that extend beyond the implementation phase, when companies are building...

Lattice-Reduction-Aided Receivers for MIMO-OFDM in Spatial Multiplexing Systems

Orthogonal Frequency Division Multiplexing OFDM significantly reduces receiver complexity in wireless broadband systems and therefore has recently been proposed for use in wireless broadband multi-antenna MIMO systems. The performance of maximum likelihood detector in MIMO-OFDM system is optimal, however, its complexity, especially with higher order constellation is prohibitive. A number...

Reducing Retail Complexity

The complexity of much of today's disjointed enterprise infrastructure software impedes retailers' business agility and productivity. Customers have spoken, saying, "The software industry has made licensing far too complex"; "The costs of selecting, acquiring, and deploying software are too unpredictable"; and "The industry's mismatched release schedules create complexity for us."...
