CDMA........

Answer 2

Answer:

CDMA is a term that refers to a physical layer technique.

Explanation:

• The physical layer of the Open System Interconnection Model is the initial and lowest layer (OSI Model.)
• The physical layer (also known as layer 1) enables electrical or mechanical interfaces to connect to the physical medium for synchronised communication and deals with bit-level transfer between multiple devices.
• This layer controls the majority of the network's physical connections, including wireless transmission, cabling, cabling standards and types, connectors and types, network interface cards, and more, as needed.
• The physical layer has nothing to do with the physical medium itself (like copper, fibre, etc.)
• Time and frequency multiplexing are not the same as the Code Division Multiple Access (CDMA) scheme.
• In this arrangement, a user has unrestricted access to the entire bandwidth for the duration of the session.
• Various CDMA codes are utilised to distinguish between different users, which is the main principle.
• Direct sequence spread spectrum modulation (DS-CDMA), frequency hopping, and mixed CDMA detection are often employed techniques (JDCDMA).
• In this case, a signal with wide bandwidth is generated.
• This process is carried out with the use of a code known as spreading code.
• The physical layer has nothing to do with the physical medium itself (like copper, fiber, etc.)

Hence, physical later technique is termed as CDMA.
