A new anti-interference algorithm based on correlation function to obtain the desired signal effectively from the interference environment at low signal-to-interference-plus-noise ratio (SINR) is proposed. At transmitter, the autocorrelation function of the original signal is transformed before transmission. At receiver, a mixing matrix of the desired signal and interference is calculated according to the correlation function of received signal to obtain the separation vector for interference elimination. The computer simulation and the field-programmable Gate Array (FPGA) hardware verification results show that the algorithm is not sensitive to the bandwidth of interference, and bit error rate (BER) performance degradation is only about 1 dB because of the separation residual error, as well as it is suitable for hardware realisation with low complexity.
