Codebook generating method and apparatus for MIMO channel

ActiveCN101335558AGuaranteed to fitSpatial transmit diversityError prevention/detection by diversity receptionComputing systemsTransmission matrix
The invention discloses a codebook generating method of a multi-input and multi-output channel, including the following steps: the probability distribution function of an MIMO channel is acquired by an MIMO channel transmission matrix; the mean quantization error of the system is calculated according to the probability distribution function of the MIMO channel; the codebook is acquired according to the mean quantization error of the system, and the codebook is a set of vectors which lead the mean quantization error of the system to be minimum. The invention also discloses a codebook generating device of the multi-input and multi-output channel, which comprises an acquisition module, a calculation module and a codebook determination module. The codebook acquired by the embodiment of the invention corresponds to the MIMO channel distribution function, thus ensuring that all the generated MIMO codebooks are applicable to the corresponding MIMO channel; furthermore, by the definition and the use of the unitary space distance function, the method of the invention overcomes the defect that the codebook deduction can be conducted only when the dependency of the channel is zero in the prior art.

A circuit for compressing data and a processor employing same

The present application addresses a fundamental problem in the design of computing systems, that of minimising the cost of memory access. This is a fundamental limitation on the design of computer systems as regardless of the memory technology or manner of connection to the processor, there is a maximum limitation on how much data can be transferred between processor and memory in a given time, this is the available memory bandwidth and the limitation of compute power by available memory bandwidth is often referred to as the memory-wall. The solution provided creates a map of a data structureto be compressed, the map representing the locations of non-trivial data values in the structure (e.g. non-zero values) and deleting the trivial data values from the structure to provide a compressedstructure.

Decentralized computing systems and methods for performing actions using stored private data

InactiveUS20220014367A1Key distribution for secure communicationPublic key for secure communicationEngineeringOne-time password
A distributed computing system is used to form a login network to perform an action for a user, using private data. The login network executes the verification using blockchain computing architecture, which is decentralized. The private data is stored on the blockchain in an obfuscated form. In order to compute the private data from the obfuscated form, multiple distributed private key shares are required to generate multiple decryption shares, which are combined to compute a One Time Pad (OTP). In turn, the OTP is used to obtain the private data from the obfuscated form.

Solver for a restrained deformable system with released degrees of freedom

ActiveUS20070007382A1Minimizing energyActuated automaticallyGenitals massageElement analysisEngineering
A process of using finite element analysis for determining the behaviour of a system, submitted to predetermined load and displacement boundary conditions with a degree of freedom relative to a local coordinate system released at one node of the system. For a geometrically non-linear solution scheme, a plurality of incremental steps are carried, for which computing for a finite element of the system a displacement vector at the nodes of the finite element is performed by minimizing the energy of the system. For a geometrically linear solution scheme, a single solving step is carried, for which similar steps of computing for a finite element and timely minimizing of the system's energy are performed. The step of minimizing is carried out, for a node having a released degree of freedom, in a local frame of reference, and the released degree of freedom at the node is expressed along one axis of such frame. Such hybrid reference frames allow expressing and taking into account in the global formulation the constraints of the non-released degrees of freedoms in a simple manner, without having to factorise constraints.

Co-operative memory management system

A system for memory management that comprises: a computing system having a finite amount of memory and a physical computer readable storage memory readable by a processing circuit and storing instructions for execution by the circuit to: set, by a memory coordinator, the urgency of each memory consumer; adjust, by the memory coordinator, the memory quota of each memory consumer—such that the sum of the memory quota of each memory consumer does not exceed the memory; and adjust, by each memory consumer, its memory usage in response to a quota input and an urgency input from the memory coordinator to the memory consumer. The memory is managed by a memory coordinator and memory consumers; and consumed by the memory consumers. Each memory consumer has: a memory quota, an urgency and a memory usage. Also, the urgency of each memory consumer increases as the sum of the memory usage of the plurality of memory consumers approaches the finite amount of memory.
