Abstract :
A OFDM system that encountered random phase multitone jamming is analyzed, expression reveals that the bit error rate (BER) is inverse-linear to signal-to-jamming ratio (SJR) when worst case jamming scenario occurs. However, frequency diversity with hard decision or soft decision and convolution coding can effectively alleviate the loss.
