The authors examine the performance of various types of error correcting codes under worst-case partial band noise jamming and worst-case multitone jamming using fast frequency-hopped, noncoherent M-ary frequency-shift-keying (NCMFSK) with optimum diversity. The bit-error-rate performance of some error correcting codes, which augments the results previously published on the subject, is given. New candidate codes with superior antijam performance are identified. It is concluded that, overall, the concatenated (255,241) Reed-Solomon outer code with the semiorthogonal convolutional inner code with 8-ary FSK has the best performance. If only nonconcatenated codes are considered, the rate 1/2 Trumpis code is best, and is only 0.89 dB worse than the best concatenated code.
