Abstract: A method for executing a hard disk operation command, a hard disk, and a storage medium. After an operation command is received, a target LUN in an idle state is determined; a target physical block that is to be accessed when the operation command is executed is determined from the target LUN; the operation command is stored in a processing waiting queue corresponding to a flash memory chip to which the target physical block belongs; and a working state of the target LUN is changed to a non-idle state when a quantity of operation commands that wait to be processed in a processing waiting queue respectively corresponding to each flash memory chip in the target LUN is greater than a preset threshold.

Abstract: The disclosure discloses a signal processing method for a Long Term Evolution (LTE) base station side, wherein the method includes the following steps: in a downlink signal direction, filtering downlink signals at a baseband side to remove high frequency sub-carrier components, and extracting signals from the filtered signals with an extracting frequency fsd, wherein fw?fsd<(128/75)*fw, and fw is the frequency spectrum bandwidth of the LTE; in an uplink signal direction, first performing interpolation on uplink signals to increase the signal frequency, and then filtering the signals to add high frequency sub-carrier components. The method of the disclosure can effectively reduce the transmission rate of a baseband radio frequency interface without increasing the complexity of a radio frequency side.
