%X This paper investigates the Bit Error Rate (BER) of the time-frequency 2-Dimensional Spread Spectrum (2DSS) in Additive White Gaussian Noise (AWGN) channel with the presence of multi-tone jamming. Analytical results indicate that the harmful effect caused by the multi-tone jamming can be completely eliminated when the jamming signals are placed on certain sub-carriers’ central frequencies and if the corresponding row sums of the 2-dimensional spreading code matrix are equal to zero. The simulation results are provided, which show the agreement between theoretical analysis and simulation results.
