NER
Named-entity recognition
gpt-5-mini
Instruction
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).

Target entity: Orthogonal Frequency Division Multiple Access Context triple: [Time Division Multiple Access, contrastedWith, Orthogonal Frequency Division Multiple Access]
-
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
chosen
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.
Time Division Duplex
Time Division Duplex is a wireless communication method that uses a single frequency band for both uplink and downlink by separating them in time rather than frequency.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
