Abstract: A system for sharing an antenna between multiple operators is provided. The system includes a radio frequency and digital conversion unit and an active antenna. The radio frequency and digital conversion unit is configured to convert a radio frequency signal of each radio frequency module into a digital signal, and send digital signals of a same sector to an active antenna corresponding to the sector. The active antenna is configured to perform at least one of vertical beam forming processing and horizontal beam forming processing on received digital signals according to a signal transmitting parameter that is set for each operator, convert the processed digital signals into radio frequency signals, and then transmit the radio frequency signals from an air interface.

Abstract: A method for recovering erroneous data is disclosed, the method includes: when data in a storage block that is included in a solid state disk (SSD) is read, performing a first error check on data on a certain page of the storage block to acquire erroneous data on the page; if a first number of pieces of the erroneous data on the page is smaller than or equal to a preset first threshold, performing an error checking and correction (ECC) recovery on the data on the page; and if the first number is greater than the preset first threshold, acquiring data from spare space according to a storage position of the erroneous data on the page and a fixed entry corresponding to the storage block, and replacing the erroneous data on the page with the acquired data, where the fixed entry includes a storage position of each data stored in the spare space.
