OFDM (Orthogonal frequency-division multiplexing) is the key technology to 4G in the field of mobile communication. The theory of FH_OFDM and AFH_OFDM (Adaptive frequency hopping-Orthogonal frequency division multiplexing) systems is introduced firstly in this article, and the Simulink toolbox is used to set up the simulation model for AFH_OFDM system. In this paper, we compare the BER performance...
In uplink of interleaved single carrier frequency division multiple access (SC-FDMA) systems, multiple access interference (MAI) arises from different carrier frequency offsets (CFOs) from different users at the receiver. In this paper, the performance of uplink interleaved FDMA (IFDMA) in the presence of CFOs is exactly analyzed. An expression of signal to interference plus noise power ratio (SINR)...
Multiple-input multiple-output (MIMO) single carrier frequency division multiple access (SC-FDMA), which combines the advantage of spatial and frequency diversities with frequency domain equalizers (FDE), has drawn great attention recently. Among all possible detection techniques, maximum-likelihood detection (MLD) is optimal, but its exponentially computational complexity precludes its use in practical...
