Abstract
The swift growth in multimedia technology of wireless network has made it mandatory for the efficient transmission across erratic channel. The transmission of encoded video using error control techniques is grabbing a great attention, since it works over the recovery of the lost data and errors in the bit frames which occur as a result of congestion and physical channel fading. Turbo codes are attracting researchers because of their efficient performance. The Turbo code is made up of analogous concatenation of two Recursive Systematic Convolutional (RSC) coders parted by a non-uniform interleaver. For different code rate and information block lengths greater than 104, these codes are capable of achieving low Bit-error rates (BERs) at SNRs within 1dB of Shannon’s limit. Turbo codes will assist to employ Viterbi decoders. More the number of iterations, higher is the error correction capacity and hence Turbo codes act as an elucidation for obtaining large coding gains.
