ied the discrete Fourier transform (DFT) to parallel data transmission system as part of the modulation and demodulation process. In addition to eliminating the banks of subcarrier oscillators and coherent demodulators required by FDM, a completely digital implementation could be built around special purpose hardware performing the fast Fourier transform (FFT). Recent advances in VLSI technology enable making of high speed chips that can perform large size FFT at affordable price.

In the 1980s, OFDM has been studied for high speed modems, digital mobile communications and high density reco..................[:=> Show Contents <=:]

ls spaced approximately 30 kilohertz apart. - Frequency Division Multiple Access, digital transmission technology that combines elements of TDMA and spread spectrum.

Frequency Division Multiple Access. A method allowing multiple carriers to share a single satellite transponder or range of frequencies. The transponder bandwidth is divided into sub-channels, each of which is allocated to a particular earth station (carrier). The earth stations transmit continuously and the transponder conveys several carriers simultaneously at different frequencies.

A method employed to permit several us..................[:=> Show Contents <=:]

ce (called the spreading code) that modulates a carrier, spreading the spectrum of the waveform. A large number of CDMA signals share the same frequency spectrum. If CDMA is viewed in either the frequency or time domain, the multiple access signals overlap with each other. However, the use of statistically orthogonal spreading codes separates the various signals in the code space.

CDMA Receivers
A CDMA receiver separates the signals by means of a correlator that uses the particular binary sequence to despread the signal and collect the energy of the desired signal. Other users' signals, wh..................[:=> Show Contents <=:]

rs to transmit simultaneously on one satellite transponder by assigning a specific frequency within the channel to each user. Frequency Division Multiple Access. FDMA systems transmit one voice circuit per channel. Each conversation gets its own, unique, radio channel. The channels are relatively narrow, usually 30 KHz or less and are defined as either transmit or receive channels. A full duplex conversation requires a transmit & receive channel pair. For example, if a FDMA system had 200 channels, the system could handle 100 simultaneously full duplex conversations. (100 channels for transmit..................[:=> Show Contents <=:]

GSM digital standard.

TDMA was a significant leap over the analog wireless service that was in place at the time, and it's chief benefit for carriers was that it used the available wireless spectrum much more efficiently than analog, allowing more phone calls to go through simultaneously. An additional benefit to carriers was that it virtually eliminated the criminal cell phone cloning that was popular at the time by encrypting the signal it's wireless signal.

The primary benefit for wireless users of the era was dramatically increased call quality over the scratchy, frequently garbled ..................[:=> Show Contents <=:]
