    Abstract: An improved technique involves assigning a different generator matrix to each data stripe of the redundant disk array such that all of the different generator matrices represent the same code. For example, when a k x n generator matrix G represents a linear code C , k being the block length and n the code length, then for any invertible k x k matrix P , the matrix G' = PG is also a generator that represents C . When C is a systematic code, then G consists of a k x k identity matrix representing payload data concatenated with a k x (n-k) parity matrix representing parity data. Certain matrices P represent row operations on G , meaning that the matrix G may have the columns of the identity matrix in G to different locations in G' .

    Abstract translation: 改进的技术涉及为冗余磁盘阵列的每个数据条带分配不同的发生器矩阵,使得所有不同的发生器矩阵表示相同的代码。 例如,当k×n生成矩阵G表示线性码C时,k是块长度,n代表码长,则对于任何可逆k×k矩阵P,矩阵G'= PG也是表示C的发生器。 当C是系统代码时,G由表示与表示奇偶校验数据的k×(n-k)奇偶校验矩阵连接的有效载荷数据的k×k个单位矩阵组成。 某些矩阵P表示G上的行操作,意味着矩阵G可以具有G中的单位矩阵的列到G'中的不同位置。

    Abstract: 本发明实施例提供一种Polar码的译码方法和译码器。该译码方法包括:将长度为N的第一Polar码分为相互耦合的m个第二Polar码,其中每个第二Polar码的长度为N/m,N和m为2的整数幂且N〉m;对m个第二Polar码独立地进行译码,获取m个第二Polar码的译码结果;根据m个第二Polar码的译码结果,得到第一Polar码的译码结果。本发明实施例将长度为N的Polar码分为相互耦合的多段Polar码,对分段后的Polar码独立译码,然后对独立译码的结果联合处理得到原始Polar码的译码结果,这样不必顺序地对N个比特进行译码,能够提高Polar码的译码灵活度。

    Abstract: Methods and apparatus for use in communication systems using recursive modulation schemes with a Low Density Generator Matrix code (including an irregular repeat accumulate (IRA) code) are described that have reduced complexity and thus reduced cost compared to prior art systems. A communication system is described in which the transmitter concatenates a low density generator matrix code with an accumulator followed by a recursive modulator in order to eliminate the use of an interleaver, and in which the receiver combines the decoder for the accumulator and the soft demodulator into a single joint decoder in order reduce the number of components and complexity. Another variation is also described in which the transmitter is further simplified by eliminated the accumulator altogether, and in which the receiver is further simplified by replacing the joint decoder with a soft demodulator prior to the LDGM soft decoder.

    Abstract: A method and apparatus that improves the performance of TCP (and other protocols) in a data network by segmenting the TCP path and implementing a proprietary protocol (DPR™) over the network. The DPR™ protocol provides a multiplexed tunnel for a multiplicity of TCP sessions from a client to a cloud proxy. DPR™ implements congestion management, flow control, reliability, and link monitoring. Other network protocols (such as UDP) are supported with a reliability protocol based upon network coding that improves the transmission reliability. A network and a method for transmitting processes in a network are disclosed, using deterministic coefficients for encoding packets based on network coding principles. Disclosed is a method and implementation for using deterministic coefficients for encoding packets based on network coding principles. The use of deterministic coefficients reduces the need for extra information to be transmitted to recover the lost packets and results in significantly reduced overhead and increased performance, security and reliability.
