Abstract

In order to solve the problem that the data which get from the load on the machine is vulnerable to be interrupt when it transmission by the wireless communication, making the GCS (ground control system) can not receive properly. By analyzing the link transmission error model of the downstream data, design and implement an efficient erasure coding technology in hardware. This erasure coding is based on the Vandermonde theory, using the look-up table for calculated in hardware. The way of streamlined has been adopt for the data input to output. When the frame count of input data reaches a certain number and the erasure value will be output after 8 clock cycles. Simulation results show that the proposed design erasure coding of the anti-channel interference has ability that ensure the data transmission reliable in the channel which the bit error rata is 1×10-5. This algorithm has been implemented in the hardware, which is XILINX-VIRTEX-5-XC5VSX50T. The highest resource consumption after hardware synthesized does not exceed 4%.
