An RF signal reception method includes mixing a received signal and a local oscillator signal to form a down converted signal. The down converted signal formed from the received signal is a modulated non-zero low frequency carrier referred to as a low frequency carrier desired signal. The low frequency carrier desired signal is extracted from undesired signals and interferers by using low or band-pass filters and the resulting signal is AC coupled to low frequency amplifiers for amplification. A digital representation of the low frequency carrier desired signal is then formed by digitally sampling at an analog-to-digital converter. The digitized desired signal may be further processed by digital signal processing devices for obtaining voice and/or data messages.
