摘要： The breadth-first search (BFS) starts with a root node. In the first stage, all neighbors of the root node are discovered and added to the nodes frontier. In the following stages, unvisited nodes from the neighbors of the frontier nodes are discovered and added to the frontier. To improve the parallelization of the BFS, the bottom-up search iterates over all unvisited nodes, where each unvisited node searches for its visited neighbors. Communication between nodes and clusters is pipelined with the execution of the BFS.

摘要： A system and method for providing error control coding for backhaul applications are disclosed. Data is first encoded using Reed-Solomon (RS) coding. The output RS blocks are then turbo coded. The size of the output RS blocks is selected to match the input of the turbo encoder. The bits from the RS blocks may be interleaved to create the input turbo blocks. Cyclic Redundancy Check (CRC) parity bits may be added to the data prior to RS coding.

摘要： Embodiments of the invention provide a method of decoding of hexagonal constellations. The decoding methods exploit the inherent structure of the hexagonal grid to eliminate/minimize the requirements for distance computations. A constellation which has unused constellation points is received. A plurality of lookup tables is used for indicating whether a particular constellation point is used. The lookup tables are indexed using the two integers u and v. An initial estimate ū and v is found. The euclidean distance to the immediate neighbors resulting in the immediate upper and lower integers for ū and v is computed. From the distance to the nearest neighbor, the log-likelihood ratio value is computed.

摘要： To enable lossless compression, an auxiliary bitmap is used to provide side information about the graph bitmap. Each bit in the auxiliary bitmap represents a word in the graph bitmap. A zero bit in the auxiliary bitmap means that the corresponding word in the graph bitmap is not transmitted. Therefore, it is set to the default value, λ, during decompression. This default value could be either an all-zeros word, or all-ones word depending on the BFS step. A one bit in the auxiliary bitmap means that the corresponding word in the graph bitmap is transmitted.
