摘要： A system for measuring inter-carrier interference (ICI) in an OFDM system includes a test symbol generator coupled to a transmitter of the OFDM system to generate an N*N orthogonal matrix having N*N test symbols, and to send the test symbols in a test symbol stream via the transmitter to a receiver of the OFDM system. The N*N test symbols are arranged by the test symbol generator into an N*N orthogonal matrix before being sent to the receiver. The system also includes an ICI measuring module coupled to the receiver to detect the N*N test symbols received in the receiver and to arrange the test symbols as a receiving matrix in the same way as the orthogonal matrix in the transmitter. The ICI measuring module outputs the receiving matrix as an ICI matrix of the OFDM system, wherein an element on the kth row, lth column of the ICI matrix represents interference from the lth sub-carrier on the kth sub-carrier, wherein k≠l.

摘要： The present disclosure discloses a technique for real-time batch account processing. In one aspect, a method includes: (1) receiving, by an account processing center, a marked request for batch processing; (2) caching the marked request; (3) pre-processing sub-requests of a type relating to an account that are in the marked request, including merging operations of a type for processing for the account; and (4) processing the marked request, including the pre-processed sub-requests, to provide a processing result to a corresponding client. The request for batch processing can be directly submitted at the client or submitted by a client through an interface that is provided to the client for submitting a request including the request for batch processing. When submitting the request for batch processing, the client can wait for the processing result online, and obtain the processing result at real-time. Further, when receiving the request for batching processing, the account processing center can pre-process it, e.g., merging operations for the same account, and thus increase efficiency of batch processing.

摘要： Concurrent processing of business transaction data uses a time slice-centered scheme to cope with the situation where multiple requests demand a same resource at the same time. The method divides the processing time into multiple time slices, allocates each request to a corresponding time slice, and iteratively processing requests according to their corresponding time slices. The method does not require the requests to be processed one by one, and therefore does not cause a situation where other requests have to wait until the current request has been completely processed. Moreover, if a certain time slice has been allocated multiple requests of a same type, the requests are collectively processed as if they were a single request to reduce the frequencies of resource locking and unlocking, as well as the waiting time in a queue for resource access.

摘要翻译： 业务交易数据的并发处理使用时间片为中心的方案来应对多个请求同时需要相同资源的情况。 该方法将处理时间划分为多个时间片，将每个请求分配给相应的时间片，并根据其对应的时间片迭代处理请求。 该方法不需要逐个处理请求，因此不会导致其他请求必须等到当前请求完全处理的情况。 此外，如果某个时间片已经被分配了相同类型的多个请求，则这些请求被集中地被处理，就像它们是减少资源锁定和解锁频率的单个请求一样，以及队列中的资源等待时间 访问。
