  • Patent number: 11996874
    Abstract: Systems and methods comprising: receiving a signal (S) having a first interfering signal component (FISC); generating a replicated SOI (RSOI); and iteratively performing a process to obtain residual errors for FISC. The process involves: modifying an amplitude of RSOI; obtaining a reference signal (RS) by removing RSOI with the modified amplitude from S; analyzing frequency of RS to obtain an estimated carrier frequency and an estimated symbol rate for FISC; generating a remaining signal by removing, from FRS, a signal having the estimated carrier frequency and symbol rate; and determining a residual error of the remaining signal. Parameters for FISC are then set equal to the estimated carrier frequency and symbol rate that are associated with a lowest residual error. The parameters may be further refined in accordance with another process which involves iteratively modifying a symbol rate of FISC. Yet another process may be performed to determine filter parameters.

  • Patent number: 11700024
    Abstract: Systems and methods for mitigating an effect interference. The methods comprise: receiving, by a device, a signal comprising a plurality of signal components; determining whether each signal component has a sufficient reconstructability; reconstructing each said signal component that was determined to have sufficient reconstructability using the received signal or an at least partially clean signal with other signal component(s) removed from the received signal; and using the reconstructed signal components to generate a modified received comprising the received signal with the signal components removed therefrom that (i) are devoid of a signal of interest and (ii) have sufficient reconstructability.

  • Publication number: 20230171137
    Abstract: A Radio Frequency (RF) receiver may include a lower-order phase shift keying (PSK) demodulation circuit configured to generate at least one locking parameter when performing a lower-order PSK demodulation of an RF receive signal having an interfering PSK signal component. A higher-order PSK demodulation circuit has a higher order than the lower-order PSK demodulation circuit, and locks to the RF receive signal using the at least one locking parameter from the lower-order PSK demodulation circuit. The higher-order PSK demodulation circuit performs the higher-order PSK demodulation of the RF receive signal based upon locking to the RF receive signal to determine the interfering PSK signal component.
