PROJECT TITLE :

Image transmission using unequal error protected multi-fold turbo codes over a two-user power-line binary adder channel

ABSTRACT:

Impulsive noise is one amongst the foremost challenges for reliable transmission over power lines. Interleavers offer higher protection against the impulsive noise by dispersing data across the channel and spreading the burst of errors over multiple codewords. Multi-fold turbo (MFT) coding may be a technique that improves the Communication reliability using multiple interleavers. In the MFT codes, every information subsequence is equally protected. For applications in which knowledge constitute info with varied levels of importance, it's intuitive to offer the additional necessary subsequence, a stronger protection. A changed kind of the MFT codes capable of providing unequal error protection over a two-user power-line binary adder channel is proposed here. As a benchmark, 2 take a look at pictures are transmitted across the channel. The trellis-primarily based iterative algorithm is modified for the two-user state of affairs to decode the received signal. The simulation results show a gain of 1.five dB for the changed MFT code over the traditional turbo codes for every of the transmitted images. A gain of 2 dB is also recorded for the most protected part of every image over the least protected components.
