| Abstract: |
| An implementation scheme of the DS - FFH/MSK modulation is given. Under different interference backgrounds, the performance of Link16 based on this scheme is analyzed in the view point of bit error rate. The expression of bit error rate is derived with the existence of several different kinds of jamming signals. Computer simulations are also given. |
| Key words: data link spread spectrum modulation anti - jamming BER |
