چکیده
Flexible and low-complexity variable rate coding schemes based on rate-compatible convolutional codes are presented. The codes have a wide range of code rates and are optimized for good performance on both AWGN and Rayleigh fading channels. Furthermore, the application of these codes for rate matching, combined coding and spreading in a DS-CDMA system and hybrid type-II ARQ schemes are demonstrated. Very long constraint length convolutional codes with sequential decoding is proposed and shown to be suitable for high performance services in wireless systems.

متن کاملA 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...
متن کاملModern coding schemes for unequal error protection
In this thesis, we present modern and efficient channel coding techniques for the protection of user data with heterogeneous error sensitivities. Especially multimedia data being transmitted through communication networks often consist of unequally important parts, such as header information, essential payload, and additional data for increased quality. Protecting all data equally makes the tra...
متن کاملAchieving Unequal Error Protection via Woven Codes: Construction and Analysis
In this paper several rate R = 2/5 convolutional encoding matrices with four states are used to illustrate how unequal error protection can be achieved for the different positions in the code sequences as well as in the information sequences. Free outputand input-distances and active burst outputand input-distances are computed. Typically a single code cannot combine a large free outputor input...

633 Serial Unequal Error-Protection Codes based on Trellis-Coded Modulation David K. Asano and Ryuji Kohno Abstract| Unequal error-protection (UEP) codes that are designed using trellis-coded modulation (TCM) are proposed for use with a single data stream consisting of information with two levels of importance. To achieve UEP, the proposed scheme encodes the data according to the importance of ...
