A novel MDC algorithm based on discrete cosine transform (DCT) and the set partition in hierarchical trees (SPIHT) is proposed in this paper. Different from the commonly used DCT algorithm, all the transformed coefficients are reshaped into the wavelet decomposition structure to facilitate the use of the SPIHT algorithm. Then the direction-based information is used to form the three different channels...
With dramatic scaling in feature size of VLSI technology, the capacity of on-chip L2 cache increases rapidly, how to guarantee the reliability of large capacity L2 cache has become an important issue. However, increasing the reliability of L2 cache tends to reduce its performance and brings more power consumption. This paper presents ECC-Cache, a novel low power fault-tolerant architecture which divided...
This paper reports on the performance of the space time block coded MIMO system with spatial redundancy which is accomplished using a larger than required numbers of antennas. The proposed scheme guides the transmitted power onto the RF branches with higher gain coefficients. The carried out theoretical analysis shows that the scheme can achieve higher channel capacity and lower symbol error rate...
This paper proposes C&M, a novel network coding scheme to deal with both inter-flow and intra-flow traffic in wireless networks. Prior work on wireless network coding design belongs to either inter-flow network coding or intra-flow network coding. C&M attempts to combine advantages of both network coding approaches to develop a more efficient network coding scheme. Based on COPE, C&M allows...
