Linear feedback shift register (LFSR) has been widely applied in BCH and CRC encoding. In order to increase the system throughput, the parallelization of LFSR is usually needed. Previously, a technique named state-space transformation was presented to reduce the complexity of parallel LFSR architectures. Exhaustive searches are performed to find good transformation matrix candidates. This brief proposes...
The emergency of mass-data-processing applicationsencourages the exponential growth of high-speed communicationtechnologies. In order to ensure the accuracy of data transmission, product codes have attracted much attention in bothcommunications and storage industries. It is well-known thatproduct codes are very efficient in achieving high coding gain andhigh throughput at low computation complexity...
Along with the rapid development of communication technologies, forward error correction (FEC) codes have drawn a lot of research interests recently. Several modern codes such as super product code and staircase code are proposed for 100Gbps optical transport network. A kind of tail-biting code with some improvements on staircase code is proposed in this paper. This code not only possesses the high...
Retrieving book covers in web images or in specified database has a wide application prospect, from electronic commerce to picture search. We describe a book cover retrieval system based on enhanced SIFT descriptor by incorporating “binary string” descriptor. Furthermore, a new error recovery based on angle difference of the matching pairs is integrated into the SIFT matching method. Experiments demonstrate...
