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. |
