Dynamic Subcarrier Allocation for Real-Time Traffic over Multiuser OFDM …

WebOFDMA is essentially a type of OFDM for multiple users. It allocates in both the time domain and the frequency domain, allowing for multiple users—even those with widely varying use patterns or data loads. By comparison, OFDM can allocate only sequentially. What problems does OFDMA solve? WebThe first task to consider is that the OFDM spectrum is centered on fc; i.e., subcarrier 1 is 7.61 2 MHz to the left of the carrier and subcarrier 1,705 is 7.61 2 MHz to the right. One simple way to achieve the centering is to use a 2N-IFFT [2] and T/2 as the elementary period. As we can see in Table 1, the OFDM symbol duration,
