Abstract [en]

There are two typical interference problems in a multi-radio platform, i.e. blocking due to the saturation of the front end of a receiver by the high power radiation from another transmitter, and desensitization of the receiver by the in-band noise generated by the other transmitter. The UWB device is not an exception.

In the coexistence study, two different development kits containing a UWB radio are investigated. The UWB devices cause a raised noise floor and generate severe spurious emissions into the receiver bands for GSM, UMTS, Bluetooth and 802.11b. Consequently this results in degradation of the sensitivity performance of these receivers. Based on measurements performed, the solution for this problem was found by inserting a band-pass filter or a high-pass filter at the transmit path of the UWB device.
