Autor: Eric A.M. Klumperink, Zhiyu Ru, N.A. Moseley, Bram Nauta

Publikováno v: IEEE journal of solid-state circuits, 44(12), 3359-3375. IEEE

—A software-defined radio (SDR) receiver with improved robustness to out-of-band interference (OBI) is presented. Two main challenges are identified for an OBI-robust SDR receiver: out-of-band nonlinearity and harmonic mixing. Voltage gain at RF is

A Two-stage approach to harmonic rejection mixing using blind interference cancelling

Autor: Eric A.M. Klumperink, N.A. Moseley, Bram Nauta

Publikováno v: IEEE transactions on circuits and systems I: regular papers, 55(412/10):10.1109/TCSII.2008.926796, 966-970. IEEE

—Current analog harmonic rejection mixers typically provide 30–40 dB of harmonic rejection, which is often not sufficient. We present a mixed analog-digital approach to harmonic rejection mixing that uses a digital interference canceler to reject

Publikováno v: IEEE transactions on broadcasting, 54(3), 356-370. IEEE

A novel low-mast low-power Terrestrial Digital Audio Broadcasting (T-DAB) single frequency network topology is described and evaluated in this paper. For this purpose, a pilot network (band III and L-band) was constructed in Amsterdam, the Netherland

Publikováno v: International Journal of Distributed Sensor Networks, Vol 11 (2015)
International journal of distributed sensor networks, 2015:791046. Sage

We describe the design and evaluation of an integrated low-cost underwater sensor node designed for reconfigurability, allowing continuous operation on a relatively small rechargeable battery for one month. The node uses a host CPU for the network pr

Wideband direct-conversion harmonic-rejection (HR) receivers for software-defined radio aim to remove or relax the pre-mixer RF filters, which are inflexible, bulky and costly [1,2]. HR schemes derived from [3] are often used, but amplitude and phase

A Spectrum Sensing Technique for Cognitive Radios in the Presence of Harmonic Images

Autor: N.A. Moseley, Bram Nauta, Eric A.M. Klumperink

Publikováno v: Proceedings of the 2008 IEEE Dynamic Spectrum Access Networks Conference (DySPAN)

—Harmonic downmixing is an important effect that must be taken into account when performing sensitive spectrum sensing using direct-conversion receivers. When the local oscillator waveform contains harmonics of the fundamental frequency, the quadra

The effects of nonlinear power amplifiers on the of a HiperLAN/2 system

Autor: Roelof Schiphorst, N.A. Moseley, Cornelis H. Slump

Publikováno v: 2nd IEE/EURASIP Conference on DSPenabledRadio.

Real-world power amplifiers (PAs) are weakly nonlinear. The nonlinear behavior causes subcarrier intermodulation in OFDM based transmitters. This paper shows the results of simulations performed on a software HiperLAN/2 system with a nonlinear power
