Feature of the book include: * Unique presentation-like style for summarising main aspects* Practical issues for implementation of coding techniques* Sound theoretical approach to practical, relevant coding methodologies* Covers standard coding schemes such as block and convolutional codes, coding schemes such as Turbo and LDPC codes, and space time codes currently in research, all covered in a common framework with respect to their applications. This book is ideal for postgraduate and undergraduate students of communication and information engineering, as well as computer science students. It will also be of use to engineers working in the industry who want to know more about the theoretical basics of coding theory and their application in currently relevant communication systems
