Abstract Based on the characteristics of Frequency Hopping(FH) system, the union-upper-bound of Block Turbo Codes (BTCs) in the short wave FH system is analyzed and deduced. The union-upper-bound equation for BTCs is given out in the barrage jamming. The numerical simulation of the BTCs is performed in short-wave jamming channel. When the signal-to-jamming ratio is 30dB, and signal-to-noise ratio is 20dB, simulation results show that using BTCs in FH system can reduce the bit error rate from 10-3 to 10-5.
