recovering the information content from modulated carrier wave
its nothing but modulation and demodulation. modulation of the message is done in transmitter side and demodulation is done at receiver side and retrieving the original message.

In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.
The word "modem" comes from the contracting of the two wordsmodulator, and demodulator.MOdulation DEModulation
Digital demodulation is the process of extracting the original digital information from a modulated signal. It involves reversing the modulation process used to encode the data onto a carrier wave, allowing the receiver to interpret the transmitted information accurately. Techniques such as phase shift keying (PSK) or frequency shift keying (FSK) are commonly employed in digital demodulation to recover the original bit stream. This process is essential in various communication systems, including digital radio, satellite communication, and data transmission over the internet.
The blended word for modulation and demodulation is "modem." A modem is a device that modulates digital signals into analog signals for transmission and demodulates received signals back into digital form. This process enables communication over various types of networks, such as telephone lines and broadband connections.

Matlab has a built-in function called "demod" in the communications (signal processing) toolbox where you can specify 'fm' for frequency demodulation.
