Multiple-access techniques aim to share a channel between two or
more signals in such a way that each signal can
be received without interference from another. For example, this can
be achieved by ensuring that only one signal is present
on the channel at any time. It can also be
achieved by ensuring that each signal is made up of
non-overlapping frequency components, that is, each signal lies in a
different part of the electromagnetic spectrum.
Multiple access in a
CDMA network uses a combination of frequency division multiple access (FDMA), code division multiple access (CDMA) and frequency
division duplex (FDD).
