Modulation describes a range of techniques for encoding information on a
carrier signal, typically a sine-wave signal.
Modulation techniques include:
Modulation is frequently used in conjuction various channel access methods, such as
- [Frequency division multiple access]?
- [Time division multiple access]?
- [Code division multiple access]?
- [Space division multiple access]?
Where these methods are used for dividing forward and reverse communication channels, they are known as duplexing methods, such as:
- [Time division duplex]?
- [Frequency division duplex]?
