Abstract
Systems, methods, apparatuses, and computer program products for interference cancellation (IC) are provided. One method includes detecting, by a receiver, a synchronization signal with most power in correlation peak and obtaining the network identity and a location of a corresponding synchronization signal in a received signal. The method may further include extracting a corresponding portion of the received signal that corresponds to the location of the interfering synchronization signal, passing the portion of the received signal through fast fourier transform (FFT) and multiplying result with corresponding frequency-domain conjugated reference synchronization signal to produce channel estimate H, passing the channel estimate H through inverse fast fourier transform (IFFT) to produce channel estimate h, truncating h to a length x, obtaining an estimate of the interfering signal by filtering the time-domain reference synchronization signal by the truncated h, and performing interference cancellation by subtracting the estimated interfering signal from a received signal at said location.
