Do demodulation task for a block of subcarriers (demul_block_size)

Parameters

tid

task thread index, used for selecting spm_buffer and task ptok

offset

offset of the first subcarrier in the block in data_buffer_ Buffers: data_buffer_, spm_buffer_, precoder_buffer_, equal_buffer_, demul_hard_buffer_ Input buffer: data_buffer_, precoder_buffer_ Output buffer: demul_hard_buffer_ Intermediate buffer: spm_buffer, equal_buffer_ Offsets: data_buffer_: dim1: frame index * # of data symbols per frame + data symbol index dim2: transpose block index * block size * # of antennas + antenna index * block size spm_buffer: dim1: task thread index dim2: antenna index precoder_buffer_: dim1: frame index * FFT size + subcarrier index in the current frame equal_buffer_, demul_buffer: dim1: frame index * # of data symbols per frame + data symbol index dim2: subcarrier index * # of users Event offset: offset Description: for each subcarrier in the block, block-wisely copy data from data_buffer_ to spm_buffer_ perform equalization with data and percoder matrixes perform demodulation on equalized data matrix add an event to the message queue to infrom main thread the completion of this task
