Multiple Perspective
A multiple point perspective is a technique in which two or more vanishing points are used to create the illusion of depth on a flat surface

This question refers to man made space satellites. Satellites can have multiple owners between national governments, private companies, and universities.
In FDMA all users share the satellite simultaneously but each user transmits at single frequency.FDMA can be used with both analog and digital signal.FDMA requires high-performing filters in the radio hardware, in contrast to TDMA and CDMA
Frequency division is a method of separating a communication channel into multiple non-overlapping frequency bands. Each band is then used to carry a different signal or data stream. This technique is commonly used in radio communication systems to enable multiple users to share the same channel without interfering with each other.
shift registers can be used in CDMA(code division multiple access) in communication.
OCDMA: Its nothing but Optical code division multiple access or Orthogonal code divsion multiple access..
GLOBAL FOR SPECIAL MOBILE COMMUNICATION SYSTEM GSM- IS DIGITAL TELEPHONY SYSTEM THAT SUPPORTS TIME DIVISION MULTIPLE ACCESS CODE AND FREQUENCY DIVISION MULTIPLE ACCESS CODE
Code Division Multiple Access can allow for multiple levels of conversation at the same time on different lines of communication. It does this by first using conventional modulation practices, then by applying a special digital modulation technique known as Spread Spectrum.Ê It allows for spectral efficiency, voice encoding and superior coverage.
DWDM (Dense Wavelength Division Multiplexing)
All signal multiplexing techniques were invented to permit a single physical communication channel to carry multiple different signals. This reduces the investment costs in physical communication channels: e.g. long distance telegraph lines, long distance telephone lines, microwave links, orbiting communication satellites, fiber optic cable. Time Division Multiplexing can be implemented using either analog or digital signaling means.
Multiple subcarrier frequency refers to a method of dividing a single carrier frequency into multiple smaller subcarriers. This technique is commonly used in communication systems like Orthogonal Frequency Division Multiplexing (OFDM) to efficiently transmit data by dividing the available frequency bandwidth into multiple subchannels. Each subcarrier carries its own data stream, allowing for parallel transmission and improving spectral efficiency.
The dividend will be a multiple of the quotient in a division problem because the inverse of multiplication is division.
The basic difference between fdm and fdma is that fdm is used in wired system where as fdma is used in wireless communication.
CDMA-(code division multiple access), uses spread spectrum technique, which spreads the bandwidth of the data uniformly for the same transmitted power.(surce:wikipedia)
