Data acquisition joint framework and resource optimization method and system in imperfect SIC scene

The invention provides a data acquisition joint framework and resource optimization method and system in an imperfect SIC scene. According to the method, a short packet and a long data packet are allowed to be simultaneously multiplexed on the same frequency band so as to meet respective heterogeneous quality of service (QoS) requirements; short packets are decoded to achieve low latency, and superimposed long packets may then be decoded to maintain high signal-to-noise ratio (SNR) performance; meanwhile, a JSLP algorithm is proposed to combine short packet scheduling, pilot frequency length, block length and dynamic power distribution; the algorithm comprises the following steps: initializing; optimizing short packet scheduling; optimizing a pilot frequency length and a block length; optimizing dynamic power distribution; and judging whether the algorithm converges. According to the method, the maximum block error probability between the short packets is minimized, and meanwhile, the high signal-to-noise rat
