SC-FDMA Basic Function Simulation

While SC-FDMA basic function simulation is relatively simple, gaining deeper insights into its operational principles requires understanding several core concepts. First, SC-FDMA is a multiple access scheme used in LTE networks that utilizes Orthogonal Frequency Division Multiplexing (OFDM) signals, but unlike OFDM, it employs a single-carrier signal for data transmission - a distinction implementable in code through DFT-spread processing before subcarrier mapping. This approach enhances frequency domain efficiency compared to OFDM. Second, SC-FDMA incorporates Cyclic Prefix (CP) technology, which can be simulated by appending duplicated signal segments to mitigate multipath effects during transmission. Thus, although the basic simulation might be simple, comprehending these core concepts through practical coding implementations (e.g., using MATLAB's communications toolbox for CP insertion/removal and DFT operations) enables better understanding of SC-FDMA's working mechanisms and more effective real-world applications.
