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： A method and a system use buffered bookkeeping to update an account timely for a user to see the account information without having to wait until the next accounting date. The method records request events to generate a buffer record of the request events for an account having high-volume concurrent transactions, and fetches and processes the buffer record periodically at predetermined time intervals or recursively for bookkeeping of the request events in the account without waiting for the next accounting date. The transaction funds in the account are made available for inquiries and become accessible after only a short period of time upon the occurrence of the transaction. The length of the delay is configurable according to the level of concurrent transactions of the account.

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： 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.
