Abstract: Provided are an orthogonal frequency division multiplexing (OFDM) time domain windowing method and apparatus. The method includes: current OFDM symbol data is parsed according to a configuration task, and an inverse fast fourier transform (IFFT) processing is performed on the current OFDM symbol data to obtain IFFT data; a cyclic prefix (CP) is added to the IFFT data; and a time domain windowing mode of the current OFDM symbol data is determined according to the configuration task, a windowing operation is performed on IFFT data added with the CP according to the determined time domain windowing mode, and IFFT data after performing the windowing operation is output.

Abstract: Provided are a data merging method and apparatus for physical random access channel (PRACH) data merging, and a storage medium. The method includes the following. A task parameter of Current PRACH data merging is parsed. PRACH data of a to-be-merged antenna is read from a PRACH data cache. PRACH data merging between multiple antennas and/or RACH data merging within a PRACH of a present antenna are performed according to the task parameter. Merged data is output to a shared cache.
