Description: Viterbi decoder is mainly used in communication systems where error detecting and correcting is so important. This based on trailis diagram decoding methos. Which will use minimum humming distance formula to predect error and get corrected data instead of the wrong one. Main use of this type of decoding is in deep space communication. This code can transmitt 8 bit of data which is encoded in 14 bits in total while travelling through the channel. Many add , compare and units are connected together in a structure which can make branch metrix to move further, in short it is to make one pathe which can be seleted while tracking back.-Viterbi decoder is mainly used in communication systems where error detecting and correcting is so important.

Description: Viterbi decoder is used for decoding data encoded using Convolution Forward
Error Correction codes or data that suffers inter-symbol interference. They occur in a
large proportion of digital transmission. Viterbi decoders employed in digital wireless
communications are complex and dissipate large power. The proposed method focuses on
Gate diffusion input (GDI) which is a low power technique of digital circuit design.
Dynamic component of power is reduced in GDI technique as source of PMOS is not
permanently connected to Vdd.-Viterbi decoder is used for decoding data encoded using Convolution Forward

Description: GSM Channel Equalization
This application note describes the theory and implementation of GSM channel equalization and channel decoding algorithms using the Freescale MSC8126 Viterbi coprocessor (VCOP). It also examines the theory behind the soft output Viterbi algorithm (SOVA) assisted by the VCOP. Code examples illustrate how the VCOP performs channel equalization and the SOVA algorithm. A set of suggested design practices for VCOP usage is followed by a discussion of the VCOP driver, which provides a simple, easy interface to the VCOP. Examples of driver usage cover GSM equalization, channel decoding, and SOVA. The source code and the header file for the VCOP driver are also presented. Platform: |
