Do modulation and ifft tasks for one OFDM symbol

Parameters

tid

task thread index, used for selecting task ptok Buffers: IQ_data_long Input buffer: IQ_data_long Output buffer: iffted_data_buffer_ Intermediate buffer: ifft_buffer_ Offsets: dl_IQ_data_long_: dim1: data symbol index in the current frame * # of users + user index dim2: subcarrier index ifft_buffer_: dim1: frame index * # of data symbols per frame * # of users + data symbol index * # of users + user index dim2: subcarrier index dl_iffted_data_buffer_: dim1: frame index * # of data symbols per frame + data symbol index dim2: transpose block index * block size * # of UEs + user index * block size Event offset: offset Description: for each OFDM symbol, perform modulation and then ifft perform block-wise transpose on IFFT outputs and store results in dl_iffted_data_buffer_ add an event to the message queue to infrom main thread the completion of this task
