| Summary: | In this paper Frequency-Hopped Orthogonal Frequency Division Multiple Access (FH-OFDMA) system is considered. The performance of different Extending Quadratic Congruence (EQC) orthogonal hopping code patterns is examined in relation to OFDM transmission. The performance is evaluated in terms of Bit Error Rate (BER) in white Gaussian noise and Rayleigh fading. Multi-user interference (MUI) is eliminated and symbol recovery is guaranteed. The performance of FH-OFDMA system shows low bit error rate and good correlation properties under the circumference of the assumed channel.
