Orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) are generally known as the effective techniques for high data rate services. In MIMO/OFDM systems, the channel estimation (CE) is very important to obtain an

This paper presents a sigma-delta (SD) domain lowpass wave filter modeled after an analog distributed parameter filter (ADPF). The SD domain filter operating on SD modulated signals is built with two kinds of units, shift registers on which two-level

Low power RF devices, such as RFID and Zigbee, are important for ubiquitous sensing. These devices, however, are powered by portable energy sources, such as batteries, which limits their use. To mitigate this problem, this study developed RF energy h

We construct arithmetic modules for signal processing with sigma-delta modulated signal form which has advantage in signal quality over other pulsed signal forms. In the first part of this paper, adders and exponential function modules are presented
