- A Bayesian Approach to Bandwidth Selection for Multivariate Kernel Regression With an Application to State-Price Density Estimation
- Multivariate kernel regression is an important tool for investigating the relationship between a response and a set of explanatory variables. It is generally accepted that the performance of a kernel regression estimator largely depends on the choice of bandwidth rather than the kernel function. This nonparametric technique has been employed...

- 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...

- Channel Estimation Techniques for OFDM Systems
- Channel estimation is an important and necessary function for modern wireless receivers. With even a limited knowledge of the wireless channel properties, a receiver can gain insight into the information that was sent by the transmitter. The goal of channel estimation is to measure the effects of the channel on...

- 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...

- Linux Kernel in a Nutshell: Configuring and Building
- The kernel configuration is kept in a file called .config in the top directory of the kernel source tree. If one has just expanded the kernel source code, there will be no .config file, so it needs to be created. It can be created from scratch, created by basing it...

- Bandwidth Estimation: Metrics, Measurement Techniques, and Tools
- In a packet network, the terms "Bandwidth" or "Throughput" often characterize the amount of data that the network can transfer per unit of time. Bandwidth estimation is of interest to users wishing to optimize end-to-end transport performance, overlay network routing, and peer-to-peer file distribution. Techniques for accurate bandwidth estimation are...

- 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...
