Orthogonal Frequency Division Multiplexing OFDM spread spectrum technique distributes the data over a large number of carriers that are spaced apart at precise frequencies. This spacing provides multiple versions of the signal interfere with each other inter symbol interference ISI it becomes very hard to extract the original information....Orthogonal frequency-division multiplexing...OFDM Orthogonal

Orthogonal frequency-division multiplexing Answered by: deep at 7:00 AM on October 17, 2007 | deep's Q & A | Report Abuse Rate this : 0 0... Orthogonal frequency-division multiplexing (OFDM) is a interference among channels near each other in frequency. In some respects, OFDM is similar to conventional frequency-division multiplexing (FDM). The difference lies in the way in which the signals

Coarse wavelength division multiplexing CWDM is a method of combining multiple signals on laser beams at various wavelengths for transmission along fiber optic cables, such that the number of channels is fewer than in dense wavelength division multiplexing DWDM but more than in standard wavelength division multiplexing WDM.CWDM systems have channels at wavelengths spaced 20 nanometers nm apart

communication i.e. from Mobile Tower to your mobile and vice versa... CDMA uses Code Division Multiple Assess as the name itself indicates, for example you are in a hall occupied with number of people speaking Frequency Division Multiplexing in which each user is allocated a particular bandwidth till the communication is taking place. In my opinion GSM is better....simpaly is difrence cell phone is use to sim

Division Multiple Access - divides time frame of 20 miliseconds into 3 parts 6.6 milliseconds each. Caller A uses the part 1 of time frame and then stops to allow the caller B to use the part 2 of the time Division Multiple Access - allows all callers to occupy the same frequency band. Direct Sequence Spread Spectrum technology spreads the caller into entire frequency bandby multiplying it with a unique high

second. It also uses orthogonal frequency-division multiplexing OFDM, a more efficient coding technique that splits that radio signal into several sub-signals before they reach a receiver. This greatly and can move up to 54 megabits of data per second.

. In analog transmission, signals are commonly multiplexed using frequency-division multiplexing FDM, in which the carrier bandwidth is divided into subchannels of different frequency widths, each carrying a signal at the same time in parallel. In digital transmission, signals are commonly multiplexed using time-division multiplexing TDM, in which the multiple signals are carried over the same channel
