Adjacent-channel interference characterization for in-band interference excision in wireless communication systems

A method of wireless communication, implemented at a wireless apparatus operating in a time-division multiple access (TDMA) network, the method comprising:

• receiving, via an analog prefilter in a first frequency band, a first analog signal comprising a signal-of-interest and an interfering signal;
• receiving, via the analog prefilter, in an additional frequency band, an additional analog signal, wherein the additional analog signal comprises the interfering signal;
• generating, based on the additional analog signal, an estimate of the interfering signal;
• digitizing the first analog signal to generate a first digital signal;
• canceling the estimate of the interfering signal from the first digital signal to generate an estimate of the signal-of-interest;
• and
• demodulating the estimate of the signal-of-interest to generate data symbols,
• wherein a bandwidth of the analog prefilter spans the first frequency band and the additional frequency band, and
• wherein a bandwidth of the signal-of-interest is less than or equal to a bandwidth of the first frequency band.
