The sigma-delta beamsums obtained by adding the delayed 1-bit coded RF echo signals are then processed through a decimation filter to produce final beamforming outputs. Such 1-bit code streams possess very high rate, so they must be losslessly compressed before being transferred into computer to perform beamforming. During the compression, the phase information of the 1-bit code streams must be kept. Huffman coding was used to compress these high rate 1-bit code streams in this paper. The… CONTINUE READING
