We study packet detection in wireless networks in the presence of a practical analog automatic-gain-control (AGC) amplifier, which is adopted to scale the average power of received signals to an appropriate fixed level. However, when packets are not received, the input of AGC is pure noise, which has a small amplitude and may not be scaled to the desired level, due to the limited gain of AGC. In light...
This paper describes an experiment to extract the dynamic nonlinear model of a millimeter-wave communication system with ultra-wideband signal. The device under test consists of a pair of 60 GHz RF transmitter and receiver and the wireless channel between them. Input and output signals used to extract the behavioral model are the baseband signals before imported to the transmitter and after demodulated...
Ultra Wideband (UWB) technology has attracted widespread attention all over the world because of potential applications in high-rate short-range communications. The existing UWB technologies, e.g., the direct-sequence UWB (DS-UWB) and the multi-band orthogonal frequency division multiplexing (MB-OFDM), have high complexity, which results in high power consumption and cost, and limits its marketing...
