Abstract :
We present the wavelet orthogonal frequency division multiplexing (WOFDM) that in conjunction with frequency hopping can be used for synchronous code division multiple access (FH/S-CDMA). A low probability of intercept (LPI) modulation scheme based on a pseudo random selection of basis functions for modulation spanning the same frequency channel is also described
