Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: DFT-spread OFDM | Statement: [SC-FDMA, basedOn, DFT-spread OFDM]

Target entity: DFT-spread OFDM
Context triple: [SC-FDMA, basedOn, DFT-spread OFDM]

• A. 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.
• B. 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.
• C. SC-FDMA
  SC-FDMA (Single-Carrier Frequency Division Multiple Access) is a multi-carrier transmission scheme used primarily in LTE uplink that combines single-carrier characteristics with frequency-domain equalization to achieve lower peak-to-average power ratio than OFDM.
• D. MIMO
  MIMO (Multiple-Input Multiple-Output) is a wireless communication technique that uses multiple transmitting and receiving antennas to significantly increase data throughput and link reliability.
• E. Frequency Division Multiple Access
  Frequency Division Multiple Access (FDMA) is a channel access method in which the available bandwidth is divided into distinct frequency bands so multiple users can transmit simultaneously on different frequencies.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: DFT-spread OFDM
Target entity description: DFT-spread OFDM is a multicarrier modulation technique that combines single-carrier transmission with OFDM to achieve lower peak-to-average power ratio while retaining frequency-domain equalization benefits.
