Abstract
Embodiments of a receiver are disclosed that utilize enhanced metrics for demodulation and soft bit information generation in the presence of a non constant envelope modulated interfering signal. In general the receiver includes a downc onverter and a demodulator. The downconverter receives a radio frequency signal comprising a desired signal noise and a non constant envelope modulated interfering signal and do wneon verts the radio frequency signal to provide a downconveried signal The demodulator demodulates the do wncon verted signal based on a demodulation meiric that models the non constant envelope modulated interfering signal as a stationary non Gaussian random process with a probability distribution derived from a modulation constellation of a. modulation used for the non constant envelope modulated interfering signal. In one embodiment the demodulator outputs demodulated symbols in another embodiment the demodulator outputs soft bit information.
