- MediaTek relies on the Rohde & Schwarz CMP180 radio communication tester to test and verify TC-DFT-s-OFDM technology, a waveform technology proposed for 6G mobile communication networks.
TC-DFT-s-OFDM (Trellis Coded Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing) is being proposed to 3GPP as a potential candidate technology for 6G standardization.
MediaTek’s research shows that TC-DFT-s-OFDM delivers superior Maximum Coupling Loss (MCL) performance across various modulation orders, including advanced configurations like 16QAM.
Key benefits of this 6G waveform proposed by MediaTek include enhanced cell coverage through reduced power back-off requirements and improved power efficiency through optimized power amplifier operation techniques such as Average Power Tracking (APT).
TC-DFT-s-OFDM enables up to 4dB higher transmission power compared to traditional modulation schemes while maintaining lower interference levels, implying up to 50% gain in coverage area.
