    摘要: A system and method for mitigating interference of a radio frequency (RF) signal includes a receiver configured to include: a decomposition module that decomposes a received RF signal into sub-bands via a multi-stage filter, each sub-band being configured to operate on real and imaginary components of the RF signal, and each stage being scaled for separating time-frequency content of the desired signal from time-frequency content of the interference; a mitigation module that suppresses the interference of the RF signal in each sub-band by zeroing an output of a respective sub-band when the frequency content exceeds a predetermined threshold; and a reconstruction module that reconstructs the RF signal from the mitigation module minus the interference. The receiver is configured to determine whether the multi-stage filter is to be reinitialized with updated time and frequency resolution requirements to improve system response.

    摘要: Methods and apparatus in a wireless network that allow devices, such as client devices and access points (APs), having software defined radios (SDRs) to change operating behavior depending on network RF environment conditions are disclosed. The devices may be instructed to operate according to differently defined behavior profiles that may be chosen based on RF environment conditions. The profiles may be stored in a database. A particular profile may be obtained from the database for one or more devices based on an interference level within an RF environment of the devices. The profiles may be implemented to change device operating behavior so that interference is reduced or minimized in higher levels of interference. The profiles may also be implemented to change device behavior so that interference is reduced in lower levels of interference while also freeing up resources for more efficient use in the network during lower levels of interference.

    摘要: 生成ユニット(152)が、音声信号である検波信号(DTD)の周波数成分をサブバンド幅ごとに時間平均して時間平均スペクトル(TAS)を算出する。引き続き、生成ユニット(152)が、サブバンド幅よりも広い周波数幅で時間平均スペクトル(TAS)に対して周波数軸に沿った周波数平均化を行って、サブバンド幅ごとの基準エネルギー値からなる基準カーブを算出する。次に、生成ユニット(152)が、基準カーブに基づいて閾値カーブ(THC)を生成する。そして、検出ユニット(153)が、閾値カーブ(THC)を超えるエネルギー値となっている時間平均スペクトル(TAS)における周波数領域をノイズ周波数領域として検出する。この結果、周囲環境の影響でビートノイズ成分のエネルギー値や、音声信号のエネルギー値が変化しても、ビートノイズ成分が含まれるノイズ周波数帯域を適切に検出することができる。
