Introduction to Turbo Coding and Turbo Detection. Armed with soft-input soft-output decoding, powerful turbo code was born. We briefly discuss parallel-concatenated turbo coding. Iterative or turbo principle is more general than just for channel coding: iterative decoding-detection, iterative timing recovery-detection, iterative equalisation, etc.
Introduction to Computer Systems. Don Fussell Spring 2011 Topics: Theme. Five great realities of computer systems. How this fits within CS curriculum. Course Theme. Abstraction is good, but don’t forget reality! Courses to date emphasize abstraction. Abstract data types. Asymptotic analysis. These abstractions have limits.

• identify the basic elements of hardware and explain their functions and how they fit together to form an architecture • explain how data is represented, manipulated and stored within a computer system • identify and explain the functions of operating systems • explain how computers interact through local and wide area networks
A computer system consists of both hardware and information stored on hardware. Information stored on computer hardware is often called software. The hardware components of a computer system are the electronic and mechanical parts. The software components of a computer system are the data and the computer programs.
Operating System is an important core subject of computer science curriculum, and hands-on laboratory experience is critical to the understanding of theoretical concepts studied as part of this course.
Simply put, a computer is an electronic device that can accept data and instructions, process them or store them for later retrieval, and sometimes generate output (usually based on the processing) (see Figure 1.1).
