1. An anti-jamming method, comprising:

receiving a first signal at a first antenna;

receiving a second signal at a second antenna;

processing the first signal and the second signal to obtain a residual signal, wherein the processing comprises:

determining a weighting factor based at least in part on a correlation between the first signal and the second signal;

applying the weighting factor to the first signal to create a weighted first signal; and

subtracting the weighted first signal from the second signal to obtain the residual signal;

demodulating the residual signal to obtain symbol information; and

decoding the symbol information to obtain data.
