چکیده

We derive an isoperimetric theorem for sequences genenerated by feedback and consider block codes for the binary broadcast channel with two receivers and noiseless feedback. We get an outer bound by applying the isoperimetric theorem on the achievable rates for special cases of these codes with unequal error protection. We get a lower bound with a generalized Varshamov-Gilbert construction.

Exponential bounds on error probability with Feedback

Feedback is useful in memoryless channels for decreasing complexity and increasing reliability; the capacity of the memoryless channels, however, can not be increased by feedback. For fixed length block codes even the decay rate of error probability with block length does not increase with feedback for most channel models. Consequently for making the physical layer more reliable for higher laye...

A Serial Unequal Error Protection Code System using a Decision Feedback Equalizer with an Adaptive Error Prediction Filter for Fading Channels

In many information communication systems, the advantage of using unequal error protection (UEP) codes rather than equal error protection codes is that bits that are deemed to be important can be protected more than bits of lesser importance. We have studied UEP using a multilevel Trellis Coded Modulation (TCM) approach with various signal constellation sets and showed our system's effectivenes...

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Unequal Error Protection: Some fundamental limits and optimal strategies

Various scenarios are considered where some information is more important than other and needs better protection. A general theoretical framework for unequal error protection is developed in terms of exponential error bounds. It provides some fundamental limits and optimal strategies for such problems. A new class of problems called message-wise unequal error protection is also analyzed. Even f...
