چکیده
Product channel codes are proposed to protect progressively compressed and packetized images for noisy channels. Within packets, the product code uses the concatenation of a ratecompatible punctured convolutional code and an error detecting parity check code. Across packets, Reed–Solomon codes are used. Benefits include flexible choice of delay, adaptability of error protection level (i.e., unequal error protection), and scalable decoding complexity. The system outperforms the best known image coders for memoryless channels and performs well on fading channels.

Error Protection for Progressive Image Transmission over Memoryless and Fading Channels
A product channel code is proposed to protect progressively compressed and packetized image data that is transmitted across noisy channels. Across packets, the product code is composed of Reed-Solomon codes. Within packets, the product code uses the concatena-tion of a rate compatible punctured convolutional code and an error detecting parity check code. The beneets include exibility in terms o...
متن کاملSource-channel rate allocation for progressive transmission of images
Progressive image transmission is difficult in the presence of a noisy channel, mainly due to the propagation of errors during the decoding of a progressive bitstream. Excellent results for this problem are made possible through combined source-channel coding – a method that matches the channel code to the source operational rate-distortion as well as channel conditions. This paper focuses on t...
متن کاملProgressive Source-Channel Coding of Images over Bursty Error Channels
Transmission of compressed image data over noisy channels is an important problem and has been investigated in a variety of scenarios. In this paper, we propose a progressive time-varying source-channel coding system for transmitting images over wireless channels. The core result of this paper is a systematic method of instantaneous rate allocation between the progressive source coder and chann...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

This paper presents an efficient burst error spreading tool. Also, it studies a vital issue in wireless communications, which is the transmission of images over wireless networks. IEEE ZigBee 802.15.4 is a short-range communication standard that could be used for small distance multimedia transmissions. In fact, the ZigBee network is a Wireless Personal Area Network (WPAN), which needs a strong...
