Analog function computation method and system using space-time line codes

摘要

The present invention relates to a plurality of sensors and at least two sensors by performing analog function operation (AFC) using the overlapping characteristics of channels based on space-time line codes (STLC) in a communication environment where only the transmitting end knows the channel information. The present invention relates to a space-time line code-based analog function calculation method and system for compensating for distortion of a signal due to a channel by linearly combining signals overlapped between fusion centers having reception antennas. The space-time line code-based analog function calculation method according to the present invention comprises the steps of performing a pre-processing function on data measured by the sensor device (S10), and combining the channel state information of the sensor device with the data to which the pre-processing function is applied in the sensor device. It may include the step of performing space-time line encoding (STLC) (S30) and the step of transmitting the space-time line-encoded data by the sensor device through the same radio resource (S40). In addition, the fusion center receiving the superimposed signals from the plurality of sensor devices (S50), performing a linear combination (Linear combination) on the signals received at the fusion center (S60), and the linear combination is performed The fusion center may include a step (S70) of performing a post-processing function corresponding to the pre-processing function in order to perform a target result calculation on the data in the network.
