The Viterbi algorithm is the same as the binary Case with one main difference: The survivor sequences include the uncoded bits, which are decided at each trellis stage when selecting one of two parallel branches with the largest correlation metric.
Presently, only 8-PSK modulation is considered. Extensions to higher-order modulations can be implemented following a similar procedure.
xletview, for UNIX file and directory names are Case sensitive. The path to the project CVSROOT must be specified using lowerCase characters (i.e. /cvsroot/xletview)

Foreword
The four Case studies that follow each have a number of common features. They each illustrate the birth of an idea and show how that idea can be realised into a marketable product. Each Case study deals with engineering design and development issues and each highlights the importance of developing sound marketing strategies including market research. The importance of appropriate support mechanisms for young entrepreneurs is also covered. The Case studies illustrate how successful entrepreneurs deploy a range of entrepreneurial skills and know-how. Above all, the entrepreneurs are seen to have the capacity to innovate and exercise vision.
We are grateful to Liz Read, Development Manager for Enterprise and Entrepreneurship (Students) at Coventry University for providing these Case studies.
A Case Study: Replacing the persistence layer of a
Business Process Engine with JDO
The JDO specification (JSR-12) was released from the Java Community Process in April
2002. Its goal is to provide transparent persistence to Java classes. David Jordan provides
a concise introduction. Several books are becoming available that provide a more complete description of JDO3.
