“…Although the DC-, and channel-select filtering in the receiver reduces the IMD2 BB interference power by 6 dB in the two-tone signal case [15], and by about 13.4 dB [6,16,17] in the case of modulated Tx signals, the left-over IMD2 interference may lead to a severe signalto-noise ratio (SNR) degradation of the wanted Rx signal in reference sensitivity cases [18].…”

“…For modulated signals, the BB IMD2 power is modulation dependent and further reduced by the CSF. This is considered by a correction-factor which corrects the IMD2 power calculated by the two-tone formula [16,17].…”

Transceivers operating in frequency division duplex experience a transmitter leakage (TxL) signal into the receiver due to the limited duplexer stop-band isolation. This TxL signal in combination with the second-order nonlinearity of the receive mixer may lead to a baseband (BB) second-order intermodulation distortion (IMD2) with twice the transmit signal bandwidth. In direct conversion receivers, this nonlinear IMD2 interference may cause a severe signal-to-interference-plus-noise ratio degradation of the wanted receive signal. This contribution presents a nonlinear Wiener model recursive-least-squares (RLS) type adaptive filter for the cancellation of the IMD2 interference in the digital BB. The included channel-select-, and DC-notch filter at the output of the proposed adaptive filter ensure that the provided IMD2 replica includes the receiver front-end filtering. A second, robust version of the nonlinear RLS algorithm is derived which provides numerical stability for highly correlated input signals which arise in e.g. LTE-A intra-band multi-cluster transmission scenarios. The performance of the proposed algorithms is evaluated by numerical simulations and by measurement data.
