Riparian wetland ecosystems have been described as significant hotspots for carbon dioxide (CO 2 ) and methane (CH 4 ) fluxes, but their role in the release and sequestration of these greenhouse gases has been insufficiently assessed within China. The influences of vegetation and soil parameters on daily and seasonal variations in carbon flux in the Nenjiang basin, northeast China,...
Cooperative communications, where parallel relays forward information to a destination node, can greatly improve the energy efficiency and latency in ad-hoc networks. Communications using rateless codes, in which the source transmits an infinite number of parity bits to the destination until the receipt of an acknowledgement, provides a natural and efficient mechanism for accumulating information...
Low-density parity-check (LDPC) codes are playing more and more important roles in wireless communications due to their excellent error correction performance. In this paper, we study the combination of non-binary LDPC codes with M-ary orthogonal spread spectrum modulation for bandwidth efficient transmission over AWGN channel. Specifically, we investigate an algorithm for computing symbol soft metric...
