A digital communication system uses an eight-ary orthogonal signaling waveform with two-way diversity. The diversity receiver is capable of recognizing which symbols are jammed and demodulating using only the single unjammed pulse when it is available. The data is protected by a (15, 13) single-error-correcting Reed-Solomon code.
a. What is the minimum jammer duty factor that is meaningful to the jammer if the decoder uses an errors-only decoder?
b. What is the minimum jammer duty factor that is meaningful to the jammer if the decoder uses an errors-and-erasures decoder?
c. Set up all equations needed to compute pe versus S/J for a fixed value of duty factor.
