Apparatus, and an associated method, facilitates recovery of the informational content of a desired component portion of a receive signal received at a radio device. Non-desired component portions of the receive signal, such as interfering components formed as a result of adjacent-band communications. Power-level zero crossings of the non-desired component portions of the receive signal are detected. The receive signal is then sampled at the times corresponding to the zero crossings of the non-desired component portions. The resultant, sampled signal formed from such sampling excludes thereby the non-desired component portion of the receive signal.
