Abstract :
This letter describes results obtained from an experimental evaluation of field probes used to assess digitally modulated electromagnetic fields. Making use of an experimental setup specifically developed, a large number of devices with different characteristics were analyzed in the presence of three different spread-spectrum schemes: wideband code division multiple access [(W)CDMA], direct sequence spread spectrum (DSSS), and orthogonal frequency division multiplexing (OFDM). The measurement error caused by the modulation was investigated as a function of its main parameters: signal power, time variation, and occupied bandwidth.
