Tone sensing and nulling in frequency-hopped multicarrier system |
摘要 |
A method and system for removing frequencies interfering with a UWB OFDM receiver from transmission frequencies of the UWB communication. A sensing mechanism is added to the receiver that develops an energy histogram for the frequencies in a received signal and develops a tone mask for masking the interfering frequencies. The tone mask is applied after a mapping stage in the transmitter of the UWB communication and removes the interfering frequencies from the transmitted signal. Various criteria based on energy averaging are used to identify and null and remove the interfering frequencies.
