Modulation

Modulation

MobileComm Professionals, Inc.

•

Modulation is the process of varying the characteristics of high signal (carrier) in accordance with instantaneous value of low signal ( Modulating signal).

Modulation

MobileComm Professionals, Inc.

•

Signals are of low amplitude strength with low frequency (20 Hz to 20 KHz). 

To send the signal up to longer distance Modulation is required.

Depend on the Modulation: three types of Modulation schemes are introduced.

Amplitude Modulation  Frequency Modulation  Phase Modulation 

Multiple Access

Multiple Access Techniques

MobileComm Professionals, Inc.

•

Multiple Access – Achieved by dividing the available radio frequency spectrum, so that multiple users can be given access at the same time. 

FDMA - Frequency Division Multiple Access  –



TDMA - Time Division Multiple Access  –



( eg: GSM each Frequency channel is 200KHz) ( eg: GSM each frequency channel is divided into 8 timeslots)

CDMA - Code Division Multiple Access  –

(eg: IS95- Each User data is coded with a unique code)
