Low-Power Dynamic MIMO Detection for a 4x4 MIMO- OFDM Receiver

Autor: Miyazaki, Nozomi, Yoshizawa, Shingo, Miyanaga, Yoshikazu

Publikováno v: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences. (1):306-312

This paper describes low-power dynamic multiple-input and multiple-output (MIMO) detection for a 4x4 MIMO-orthogonal frequency-division multiplexing (MIMO-OFDM) receiver. MIMO-OFDM systems achieve high-speed and large capacity communications. However

Design of Integrated Variable RC Polyphase Filter

Autor: Bannai, Yuki, Tanimoto, Hiroshi, Yoshizawa, Shingo

Publikováno v: 電気学会研究会資料. ECT, 電子回路研究会. (53):37-42

RC polyphase filter(RCPF) is an analog complex filter and is used for image rejection of radio receivers. We propose a variable RCPF for automatic tuning system. Fixed capacitors and resistor arrarys are used to realize the variability. Also we propo

Linearization of stochastic flash AD converter

Autor: Sugimoto, Toshiki, Tanimoto, Hiroshi, Yoshizawa, Shingo

Publikováno v: 電気学会研究会資料. ECT, 電子回路研究会. (29):153-159

Since stochastic flash AD converters (SFADC) use statistical method, threshold voltages of SFADC are defined by comparator offsets instead of fixed reference voltages. Assuming offset variation follows a Gaussian distribution, the input range is narr
