  • Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

  • What is VHDL? VHDL is the VHSIC Hardware Description Language. VHSIC is an abbreviation for Very High Speed Integrated Circuit. It can describe the behavior and structure of electronic systems, but is particularly suited as a language to describe the structure and behavior of digital electronic hardware designs, such as ASICs and FPGAs as well as conventional digital circuits. VHDL is a notation, and is precisely and completely defined by the Language Reference Manual (LRM).

  • This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in system design. Most communications systems fall into one of three categories: bandwidth efficient, power efficient, or cost efficient. Bandwidth efficiency describes the ability of a modulation scheme to accommodate data within a limited bandwidth. Power efficiency describes the ability of the system to reliably send information at the lowest practical power level.

  • The new technologies and communications systems are being set up in all areas. It leads to treating data from different sources and for several proposes. But it is necessary to obtain only the information that is required. Digital filters, together with analogue filters, are used for these objectives. The main advantage of the digital filters is that they can be applied at zero cost and with a great flexibility.

  • Modern electronic systems are increasingly digital: digital microprocessors, digital logic, digital interfaces. Digital logic is easier to design and understand, and it is much more flexible than the equivalent analog circuitry would be. As an example, imagine trying to implement any kind of sophisticated micro- processor with analog parts. Digital electronics lets the PC on your desk execute different programs at different times, perform complex calculations, and communicate via the World Wide Web....

  • DSP System Implementation This chapter is concerned with the implementation of digital signal processing systems. It serves the purpose to make the algorithm designer aware of the strong interaction between algorithm and architecture design. Digital signal processing systems are an assembly of heterogeneous hardware components. The functionality is implemented in both hardware and software subsystems. A brief overview of DSP hardware technology is given in Section 10.1. Design time and cost become increasingly more important than chip cost.
