摘要：
Orthogonal frequency division multiple access (OFDMA) is a multi-carrier transmission technique that has been recently recognized as an excellent method for high speed bi-directional wireless data communication and it is one of the strong candidates as multiple access technique for the next generation of downlink receivers In this paper we aim to investigate the effect of fading channel on the performance of the IEEE 802.16e based OFDMA system with different code rate and modulation schemes using the bit-error rates (BER) versus the bit energy-to-noise density ratio (Eb/No) curves. The obtained graph can be used to set threshold signal to noise ratio (SNR), so that adaptive modulation schemes can be used to attain highest transmission speed with a target BER.
