- A Preliminary Checklist for Software Cost Management
- This paper presents a process framework and a preliminary checklist for software cost management. While most textbooks and research papers on cost estimation look mainly at the "Estimation" phase, this framework and checklist includes the phases relevant to estimation: "Preparation", "Estimation", "Application", and "Learning". The authors believe that cost estimation...

- Improving Channel Estimation in OFDM Systems for Sparse Multipath Channels
- This paper describes an algorithm for sparse channel estimation applicable to orthogonal frequency division multiplexing systems. The proposed algorithm uses a least squares LS technique for channel estimation and a generalized Akaike information criterion to estimate the channel length and tap positions. This effectively reduces the signal space of the...

- Project Estimation: Use Case Point Technique
- Estimates give an indicator of how long and how much effort is required to complete a project. There are many estimation methods available based upon expert opinion (e.g. Wideband delphi), estimation by analogy - similar projects and also parameterised techniques use case point. This paper presents a brief overview of...

- Generalized 8-PSK for Totally Blind Channel Estimation in OFDM
- Channel estimation in OFDM systems can conveniently be done by inserting a stream of pilot symbols at the transmitter and by using FIR interpolation filters at the receiver. Most blind channel estimation approaches are based on higher order statistics and converge slowly, making them unsuitable for mobile environments. Moreover, the...
