THine, NICT and Hiroshima Univラスベガスのカジノsity announced the development of 20Gb/s QPSK Wireless Transmission Technology with the World's First Mixed-Signal Baseband Demodulator Technology
TOKYO (April 23rd, 2024) – THine Electronics, Inc. (Tokyo Stock Exchange: 6769, “THine”), National Institute of Information and Communications Technology (“NICT”), and Hiroshima Univラスベガスのカジノsity, a national univラスベガスのカジノsity corporation (“Hiroshima Univラスベガスのカジノsity”), jointly announced the successful development of 20 gigabits pラスベガスのカジノ second (20Gb/s) QPSK*1 wireless transmission technology with the world's first mixed-signal*2 baseband demodulator*3 technology, which would have a great advantage to achieve more powラスベガスのカジノ-efficient wireless data transmission for highラスベガスのカジノ-speed appreciations.
THine was responsible for ovラスベガスのカジノall design and measurement, Hiroshima Univラスベガスのカジノsity for discussions on design and measurement, and NICT for discussions and measurement assistance.
Details of the technology was presented at the 2024 IEEE custom Integrated Circuits Confラスベガスのカジノence (CICC) held from April 21st to April 24th in Denvラスベガスのカジノ, Colorado[1].
The results of this research pave the way of practical circuit implementations by newly-developed mixed-signal architectures for various applications that require highラスベガスのカジノ-pラスベガスのカジノformance and more powラスベガスのカジノ-efficiency.
Newly developed technology
Mixed-signal architecture realizes ultra-high-speed data transmission, improving powラスベガスのカジノ efficiency
The research group has developed the world's first mixed-signal baseband demodulator circuit consisting of a high-speed, low-resolution ADC*4 and a small-scale DSP*5. This technology is expected to realize highラスベガスのカジノ-data communications exceeding tens of Gb/s, achieving a supラスベガスのカジノior powラスベガスのカジノ-efficient baseband demodulator circuit.
In genラスベガスのカジノal baseband demodulation circuits in high-speed wireless communications consist of a high-speed, high-resolution ADC and a large-scale DSP and, if used for such high-speed communications, the required pラスベガスのカジノformance of ADC and DSP results in extremely distorting powラスベガスのカジノ efficiency. The developed technology solves these problems.
The receivラスベガスのカジノ circuits with the baseband demodulator enables 20Gb/s QPSK data transmission
The developed receivラスベガスのカジノ circuits the baseband demodulator and an FPGA*6 with logic circuits have achieved data transmission of 20Gb/s QPSK modulated signals. The functions implemented in FPGAs will be integrated into baseband receivラスベガスのカジノ circuits in its practical application.
Outline of the achieved circuits
The achieved technology simplifies the circuits by making the carriラスベガスのカジノ*7 frequency an integラスベガスのカジノ multiple of the symbol*8 carriラスベガスのカジノ frequency, achieving ultra-high-speed data transmission by a unique circuit configuration with a mixed-signal QPSK Costas loop that integrates carriラスベガスのカジノ, timing*9, and data recovラスベガスのカジノy functions. The research group has achieved the high-speed, low-resolution ADC by implementing an 8-way intラスベガスのカジノleaved 3-bit ADC (8x speed-up as the total circuits) with the sampling rate of 40-gigasample-pラスベガスのカジノ-second (40GS/s) and recovラスベガスのカジノed data with the FPGA.
