field-programmable gate array is a semiconductor device containing programmable logic components called logic blocks, and programmable interconnects. Logic blocks can be programmed to perform the function of basic logic gates such as AND, and XOR, or more complex combinational functions such as decoders or mathematical functions. In most FPGAs, the logic blocks also include memory elements, which may be simple flip-flops or more complete blocks of memory. A hierarchy of programmable interconnects allows logic blocks to be interconnected as ne ....etc

The trend in VLSI towards single-chip systems leads to the integration of analog and digital functions on a single chip. Field-programmable devices also follow the same trend. Currently, there are many digital field-programmable devices in existence like Field Programmable Gate Arrays (FPGA), and more recently Field Programmable Analog Arrays have been developed. Field-Programmable Analog Array, usually abbreviated FPAA, is the analog equivalent of the FPGA, a digital programmable device. It is an integrated circuit which can be configured to ....etc

What is CRC?
A systematic error detecting code
a group of error control bits (which is the remainder --a polynomial division of a message polynomial by generator polynomial) is appended to the end of the message block
with considerable burst-error detection capability
The receiver generally has the ability to send
retransmission requests back to the data source through a feedback channel.

Steps involved
Following are the steps that are involved ....etc

ABSTRACT
Forward Error Correction techniques are utilized for correction of errors at the receiver end. Convolutional encoding is an FEC technique that is particularly suited to a channel in which the transmitted signal is corrupted mainly by additive white gaussian noise (AWGN). The Viterbi decoding is one of two types of decoding algorithms used with convolutional encoding-the other type is sequential decoding. Sequential decoding has the advantage ....etc

Design and Implementation of a Hardware Divider in Finite Field


INTRODUCTION
Division in finite fields is an important arithmetic
operation that is widely used in channel coding,
cryptography, error correction and code construction
applications. An algorithm that is suitable for hardware
implementation should require few clock cycles and
simple arithmetic operations. One such algorithm has been
proposed for modular division and its inverse in GF(p) is
