Abstract :
Frequency hopped Orthogonal Frequency Division Multiple Access (FH-OFDMA) is considered as one of the hybrid CDMA-OFDM systems. Data is transmitted through multiple access system which adopt set of frequencies on which signal can hopped. Extending Quadratic Congruence (EQC) orthogonal hopping code is used to provide a protection against multi-user interference (MUI) and extremely generated interfering (jamming) signals with finite power, whether the system is suffering from fading or not.
