Description
Summary:When measuring multicarrier communication systems such as an orthogonal frequency division multiplexing (OFDM) or UWB wireless signal, there is a problem that the effective measuring dynamic range of the measuring instrument may be reduced, since the peak‐to‐average power ratio (PAPR) of the measured signal is significantly high. In order to solve this problem, we propose a technique that maintains the measuring dynamic range by dividing the measured signal into multiple bandwidths to decrease the measured signal power. We made a prototype of the measuring equipment, confirmed the operation of the algorithm, and verified the effectiveness of dynamic range improvement is 5 to 8 dB in relation to a conventional circuit. © 2013 Wiley Periodicals, Inc.
