Target entity: SC-FDMA
Context triple: [OFDM, relatedTo, SC-FDMA]
  • A. OFDMA
    OFDMA (Orthogonal Frequency Division Multiple Access) is a multi-user version of OFDM that divides subcarriers among multiple users to enable efficient, high-capacity wireless communication in systems like LTE and WiMAX.
  • B. OFDM
    OFDM (Orthogonal Frequency-Division Multiplexing) is a digital multi-carrier modulation technique that splits data across many closely spaced orthogonal subcarriers to improve robustness against interference and multipath fading in wireless and wired communication systems.
  • C. LTE-Advanced
    LTE-Advanced is an enhanced 4G mobile communication standard that significantly improves data rates, capacity, and network efficiency over earlier LTE systems.
  • D. LTE
    LTE (Long Term Evolution) is a high-speed wireless communication standard for mobile devices and data terminals, widely used as the foundation of 4G cellular networks.
  • E. LTE-Advanced Pro
    LTE-Advanced Pro is an enhanced 4G mobile broadband technology that bridges LTE-Advanced and 5G by offering higher data rates, improved capacity, and advanced features such as carrier aggregation and enhanced MIMO.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
