摘要： Disclosed herein are an apparatus and method for enabling clients to participate in data storage in a distributed file system. The client device of a distributed file system according to the present invention includes a storage determination unit and a file reading unit. The storage determination unit determines whether first metadata information, including a global generation number of the chunk corresponding to a file to be read, has already been stored in the local storage. The file reading unit performs a read operation on the file using local data corresponding to the first metadata information if, as a result of the determination, it is determined that the first metadata information has already been stored.

摘要： Techniques are described that can be used to maximize the interference suppression capability of space-time coded systems by managing synchronous transmission signaling. To enhance the probability of the occurrence synchronous interference and accordingly increase interference cancellation capability at a receiver, a network of at least two transmitters in a network may utilize similar structured coding schemes and coordinate transmission so that the receiver receives co-channel signals synchronously.
