Abstract: A method for preparing a personalized cancer vaccine is disclosed. CTC as well as DNA and RNA or ctDNA and ctRNA are separated or enriched to a certain ratio; 13-20 types of DNAs having tumor-specific somatic mutations, RNA, or short-chain peptide, i.e., tumor neoantigen, which can cause a change in a protein sequence and can be closely bind to an human HLA type I or II receptory and TCR, and can further activate CD8+T cells or CD4+T helper cells, are separated. Further, a personalized cancer vaccine is prepared within 4-6 weeks, and is used for stimulating immune response in a cancerous object. Furthermore, antigens capable of stimulating anti-cancer immunity can be captured under an almost noninvasive condition, so that sequencing time and introduced errors can be reduced.

Power loading is performed based on the CSI on each of the multiplexed data streams. SFBC encoding is performed on the data streams for each of the paired subcarriers. Then, eigen-beamforming is performed based on the CSI to distribute eigenbeams to multiple transmit antennas. The power loading may be performed on two or more SFBC encoding blocks or on each eigenmodes. Additionally, the power loading may be performed across subcarriers or subcarrier groups for weak eigenmodes.
